What is Mendel's law ?
The two inheritance laws that Gregor Mendel found in his research with pea plants are known as Mendel's laws. The law of segregation and the law of independent assortment is these laws.
According to the law of segregation, two alleles of a particular gene separate from one another throughout the development of gametes, resulting in only one allele being present in each gamete. This indicates that just one allele from each parent is passed on to the offspring for a particular gene when the gametes combine at fertilization.
The law of independent assortment: This law states that the inheritance of one trait does not affect the inheritance of another trait. In other words, the alleles for different traits are inherited independently of one another.
Together, Mendel's laws of segregation and independent assortment provide a framework for understanding how traits are passed down from one generation to the next, and how genetic diversity is generated within a population.

which one of the following elements in the energy balance equation is under individual control?
ADH factors in the equation of energy balance are a person's personal control and do not count as an adverse effect of ephedra.
What connection exists between the amount of ADH and water reabsorption in the tubules?The kidneys are the target organ of ADH as it moves through the bloodstream. The renal tubules become more porous as a result. This implies that more water can exit the kidney tubule for selective reabsorption back into the circulation.
Does aldosterone make you more hypertensive?Your kidneys release (excrete) sodium through your urine as a result of aldosterone. Water retention results from an increase in salt in your bloodstream. The renin-angiotensin-aldosterone pathway is thus completed, increasing blood volume and blood pressure.

In rabbits, coat color is determined by one gene with at least 4 different alleles. The table shows the phenotypes for pairings of alleles.
2. What is the order of dominance of the 4 alleles?
Answer:
Full color is a dominant allele of C
Chinchilla has to have a recessive allel of c^ch
Himalayan must have a recessive of c^h
Albino has a recessive allele of c
Explanation:
In complete dominance, one allele completely masks the expression of another allele, which is evident in heter0zyg0us individuals. The order of dominance refers to which allele dominates over which. C>>C-ch>>C-h>>c.
------------------------
When genes express complete dominance, it means that the dominant allele completely masks the expression of the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
When a gene is multiallelic, we can talk about the order of dominance.
This means that one allele hides the expression of another allele, and there is a third allele that can inhibit the first two, and so on.
For a better understanding, let us analyze the rabbits' example.
The gene that codes for coat color has four alleles.
CC-chC-hcAccording to the image, we know that
⇒ Individuals that express full color have the following genotypes
C C, C C-ch, C C-h, C cWe can see that the C allele is present in all these genotypes, which suggests that this is the dominant allele and hides the expression of all the other alleles.
****C dominates over C-ch, C-h, and c alleles. *****.
⇒ Individuals that express chinchilla color have the following genotypes
C-ch C-chC-ch C-hC-ch cAs we can see, the allele C-ch is always present, meaning that it dominates over C-h and over c alleles.
*****C-ch dominates over C-h and c alleles******
⇒ Hymalayan individuals have the following genotypes
C-h C-hC-h cFrom these genotypes we can assume that C-h dominates over c allele.
⇒ Albino genotype is cc, meaning that the allele c is the recessive one.
According to this analysis, we could assume that the order of dominance is as follows,
C >> C-ch >> C-h >> cThe symbol >> means that the firts allele dominates over all the following ones.
C dominates over ⇒ C-ch, C-h, cC-ch dominates over ⇒ C-h, cC-h dominates over ⇒ cc is the recessive allele-----------------------------------

How is natural selection different from genetic engineering?
Genetic engineering uses a process of insertion of genetic material, which does not occur in nature, by a gene gun or other direct gene introduction methods, or by a specially built bacterial truck.
With the aid of sexual and asexual reproduction that occurs naturally, conventional breeding mostly relies on selection. In order to create the desired crops more quickly than through selective breeding, genetic engineering involves directly changing an organism's DNA.
Any form of selection that results from an organism's capacity for environmental adaptation is known as natural selection. Contrarily, artificial selection is selective breeding that is imposed by a third party, typically humans, in an effort to increase the frequency of desirable traits.

Where is most ATP produced in mitochondria?
Most ATP is produced in the mitochondrial matrix, which is the fluid-filled space inside the inner membrane of the mitochondria.
The process of ATP production in the mitochondria is called cellular respiration. It starts with the breakdown of glucose and other molecules in the cytoplasm by the process of glycolysis, which generates a small amount of ATP. The majority of the ATP is generated in the Mitochondria during the process of oxidative phosphorylation, where the electrons from the breakdown of glucose are passed through a series of protein complexes in the inner mitochondrial membrane, which generates a proton gradient that drives the production of ATP via ATP synthase.

Why are plants unable to grow at the bottom of lakes the water is colder at the bottom sunlight does not reach the bottom?
Because the water is so deep. There are no rooted plants to be found at the bottom of lakes because sunlight cannot penetrate that far.
Lakes obtain their water supply from three different sources: precipitation; rivers and streams; and underground water.
The size of lakes can range from very small to very large. They can be quite deep, or they can be only moderately so. Ponds are frequently used as a synonym for lakes that have depths of less than six or seven feet and support plant life on the bottom.
The changing of the seasons can bring about significant fluctuations in temperature for the lakes that are found in certain temperate regions.

If an organism has 50 chromosomes, how many chromosomes will the gametes have after undergoing meiosis
If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.
Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.
According to the question, if a diploid number of an organism = 50.
This means that 2n = 50,
n = 25.
As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.
Therefore, if an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.

The following are included in Mendel's theory: A pair of components regulate traits (known as genes). One gene is inherited from each parent for each trait. Every quality is passed down from one generation to the next.
During the development of gametes, genes divide. When two genes are in direct opposition to one another, one gene may be expressed while the other is hidden.
A trait may not manifest in an individual but can still be passed on to the next generation, and the genes for each trait separate themselves during gamete formation. Individuals inherit one such unit for each feature from each parent.

How the respiratory system and circulatory system work together to supply the body with oxygen and to remove waste from the body?
Together, the circulatory and respiratory systems assist eliminate waste carbon dioxide from the tissues and deliver oxygen to the tissue.
The respiratory system is the one that helps to inhale oxygen and exhale carbon dioxide. And the circulatory system is the system that helps to supply oxygen from the lungs to tissues and helps to remove carbon dioxide from the tissue via the lungs. Both these process helps to supply oxygen in this way and helps to remove carbon dioxide as a waste.
First, the oxygen inhaled will be transported to the lungs and this oxygen will be exchanged with the blood that brings the waste (CO₂) from the tissue via the heart. Then, the oxygen will be transported to the heart from where the oxygenated blood will be supplied to the tissues. And the waste from the tissue will be carried via deoxygenated blood.

What are two variations of fur color in cats?
There are two basic colors of cats, black and red. These are called “dominant” colors. The color of all cats relates to these two colors in some way, by changing the color or covering it up. There is also a “dilute” of each color.
Generally, the colours, which can be termed differently depending on the breed, are: white, red, blue, black, cream, cinnamon, fawn and brown. The colour of a cat depends completely on genetics. The two primary colours in cats are black and red. There are six varieties of cat fur patterns. These are Tabby, Solid, Bicolor, Tricolor, Tortoiseshell, and Colorpoint.
A cat displaying a dominant color (black, red, tortie, etc.) must have a parent which displays a dominant color. Two recessive color parents (cream, blue, etc.) cannot produce an offspring of a dominant color (black, red, etc.).

After jogging in place for two minutes, Pauline & Jerry noticed that they were out of breath. Explain why their bodies needed more oxygen while exercising.
Answer:
Jogging (exercising) increases the metabolic rate in the organism, and hence, its oxygen necessities. The more ATP the body consumes, the more oxygen it needs.
Explanation:
Oxygen and glucose are the basic components to produce energy. Activities such as heart bombing, or pulmonary inhaling-exhaling, among others, constantly consume energy, which is why more oxygen is needed.
While jogging, muscles need to consume more oxygen to produce ATP as a source of energy. When exercising, muscles work harder and faster than while in rest. More ATP is needed as the metabolic rate increases. Cells produce more ATP to cover the increase in metabolic rate. But to produce ATP, cells need to consume more oxygen. The more ATP the body consumes, the more oxygen it needs.
Oxygen gets to the muscle cells and other destinies through the bloodstream. Most of the oxygen joins hemoglobin molecules. While the body is at rest, 20-25% of hemoglobin molecules provide oxygen to the tissues, and the rest is stored as a reserve.
While exercising, the concentration of oxygen-hemoglobin in the bloodstream sharply decreases because the body needs more energy. As it consumes energy, it needs to get more oxygen to restore ATP. The organism needs more oxygen to satisfy its higher necessities for the molecule.
Zooplankton populations in Lake Erie and the Hudson River have declined by up to 70% since the arrival of zebra mussels because ________. Group of answer choices Zebra mussels feed on phytoplankton, which zooplankton need as a food source Zooplakton are reduced due to predator mediated competition Zebra mussels block sunlight penetration into lakes and thus prevent zooplankton from photosynthesizing Zebra mussels prey exclusively on zooplankton Zooplankton are replaced due to competitive exclusion
Answer:
Zebra mussels feed on phytoplankton, which zooplankton need as a food source.
Explanation:
The population of zooplankton in Lake Erie and the Hudson River declined due to the arrival of zebra mussels because Zebra mussels feed on phytoplankton, which is the main source food of zooplankton. So due to limited or scarcity of food in the environment, the zooplankton die due to hunger that leads to the decrease of population of zooplankton in that environment.
