how is the scientific method used in earth science (it was due yesterday)
Answer: The steps used in scientific methods are to ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate results. A controlled experiment tests only one factor at a time so that scientists can determine the effects of changes to just that one factor.
Answer:
The scientific method is the gold standard for exploring our natural world. You might have learned about it in school, but here’s a quick reminder: It’s the process that scientists use to understand everything from animal behavior to the forces that shape our planet—including climate change.

Phloem is used to transport sucrose and amino acids in plants. Sucrose is a carbohydrate. Describe the uses of carbohydrates and amino acids in plants.
Answer:
1. carbohydrates help to produce a part of cellulose. carbohydrate produces the vital source of energy, carbon skeletons for organic compounds, and storage of components.
2. Amino acids help in the ion transportation, modulation of stomatal opening, maintaining the level of detoxification.
in the study of genetics the offspring of the p generation is referred to as the
Answer:
F1 Generation
Explanation:
In the study of genetics the offspring of the P generation is referred to as the F1 generation.
In the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring. Their genetic makeup depends on their parents.
What is inheritance?Inheritance explains how the genes from the parents pass down to the offspring. An example is when both parents are tall because they are purebred, then all the F1 offspring are tall.
The T is represented by tall, and the t is represented by short. TT is purebred tall, and tt is purebred short. When two parents (P generation) are heterozygous for tallness, such as Tt, each will produce gametes such as T and t. From these gametes, three types of individuals are formed, such as purebred tall (TT), heterozygous tall (Tt), and purebred short (tt). These are called F1 offspring.
Hence, in the study of genetics, the offspring of the P generation are referred to as the F1 offspring, or first fillial offspring.

2: 1. Body cells make up the body of any multicellular organism. On the other hand, a gamete is a sex cell that can either be a sperm or egg cell.
2. Body cells undergo the process of mitosis while gametes undergo a process called meiosis.
3. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
3. Identical twins
4. nucleotide triplets
5. A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organism's cell and also pass genetic traits to offspring. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A, C, G, T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).
Explanation:
Which are examples of active transport?
Select all that apply.
exocytosis
phagocytosis
diffusion
pinocytosis
Answer:
Exocytosis, phagocytosis, and pinocytosis
Explanation:
Active transport is when energy is used to move substances across the cellular membrane.
Exocytosis requires energy to remove materials from the cell; it is active.
Phagocytosis also requires energy; it is active.
Diffusion isn't active because it moves materials down their concentration gradient and therefore it doesn't require energy.
Pinocytosis is a form of endocytosis and requires energy; it is active.

▶ Global warming can cause sea levels to rise dramatically. In many places, coastal areas have already been flooded. Global warming could result in wide ranging effects on rainfall patterns, agriculture, forests, plants and animals. Majority of people living in regions which are threatened by global warming are in Asia. A recent climate change report gives us only a limited time to keep the greenhouse gases at the present level. Otherwise, the temperature may rise by more than 2 degrees Celsius by the end of the century, a level considered dangerous.______________________________

In a forest community, a shelf fungus and a slug live on the side of a decaying tree trunk. The fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. These organisms do not compete with one another because they occupy
A. the same habitat, but different niches
B. the same niche, but different habitats
C. the same niche and the same habitat
D. different habitats and different niches
The shelf fungus and slug in the forest community do not compete with each other as they have the same habitat, but different niches. Thus, option A is correct.
What are habitat and niche?Habitat is defined as the place where the species resides while the niche is the role of the specific organisms or the species in that particular habitat or environment. The niche includes the impact of the species on the habitat.
The shelf fungus and the slug both live on the side of the tree and hence have the same habitat but the fungus takes minerals from the tree and the slug from the algae making them differ in the niche.
Therefore, the fungus and slug have the same habitat but different niches.

Which of the following statements defines ovulation?
Ovulation is when an immature ovum develops into a mature ovum.
*Ovulation is the release of a mature ovum, which occurs once each month.
Ovulation is the production of an ovum that occurs each month.
Ovulation is the monthly discharge of the uterine lining.
Answer:
b. Ovulation is the release of a mature ovum, which occurs once each month.
Explanation:is correct. post protected
Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.
What is ovulation?The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.
Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.
Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.
Thus, the correct option is B.
