They calculated the radius of the Sun to be 696,342 km (432,687 miles) with a margin of error of only 65 km (40 miles).

1. Using what you know about protein synthesis l, explain the cause of sickle cell anemia.
2. What evidence supports your explanation?
3. What is the relationship between the structure of the red blood cell and it’s function?
4. How does the shape of the red blood cell affect its function in the case of sickle cell anemia?
Answer:
Due to mutation of the HBB gene.
Explanation:
This causes a change in amino acids which are the building blocks of proteins. Therefore the proteins stick together and form a fiber that changes the shape of the red blood cell making them more fragile.
Evidence that supports my explanation
People with Sickle cell anemia cannot contract malaria since they have low surface area for hemoglobin retention.
Relationship between the structure of the red blood cell and it’s function
It has a biconcave shape with a large surface area to increase space for parking hemoglobin.
How the shape of the red blood cell affect its function in the case of sickle cell anemia
In the case of sickle cell anemia, the shape of the red blood cell becomes sickle like thus reducing the surface area for packing of hemoglobin.
What are the possible offspring of purple flower and white flower?
The phenotypic ratio of purple-flowered to white-flowered offspring will be 3:1. Hence 75% offsprings will be purple.
Genetics is the study of the genes, the genetic variation, and the heredity in the organisms. It is an important topic in biology because heredity is fundamental to organism evolution. In the nineteenth century, Gregor Mendel, a Moravian Augustinian monk working in Brno, was the first to do scientific study on genetics.
The study of genetics focuses on the effects of individual genes or groups of genes in health and disease. Understanding genetic variations and anomalies is critical for learning more about health promotion and disease prevention. In genetics, the phenotype is the set of observable traits or attributes of an organism. The term refers to the anatomy, developmental processes, biochemical and physiological characteristics, behaviour, and behavioural results of an organism.

In a diploid organism, two alleles for a particular gene are expressed and interact to produce physical traits. A species' observable characteristics are referred to as its phenotype.
The genotype is the genetic composition of an organism, which includes both the alleles that are physically expressed and those that are not. Mendel's hybridization studies show how phenotype and genotype differ from one another. For instance, the diploid genotypes of the plants in the P, F1, and F2 generations are related to the phenotypes that Mendel observed in his crosses between pea plants with different features. We shall utilize seed color as an example, which was Mendel's second feature of study. Two alleles of a single gene control the color of seeds.

Answer:
Un nucleótido se forma por la unión de una base ___nitrogenada___, un azúcar llamada _____ribosa (en ARN) y desoxirribosa (en ADN)____ y un grupo __fosfato__.
Explanation:
La información genética utilizada durante la sintesis proteica es almacenada en secuencias cortas de tres nucleotidos llamadas codones de mARN. Cada codon representa uno de los 20 amino ácidos utilizados para construir las proteinas.
Los nucleóticos son subunidades o monómeros compuestos por una molécula de azucar llamada ribosa (ARN) o desoxirribosa ADN), la que se encuentra unida a un grupo fosfato y a una base nitrogenada. La secuencia de nucleóticos en cadena se denomina polímero (compuesto por mas de dos monómeros). Diferentes nucleotidos unidos por sus extremos componen las cadenas de ADN y ARN.
Las bases nitrogenadas que se utilizan para la sintesis de ADN y ARN pueden ser agrupadas en purinas o pirimidinas.
ADN → Formado por bases → Adenina y Guanina → Purinas
→ Timina y Citosina → Pirimidinas
Adenina siempre se empareja con Timina, mientras que Guanina se empareja con Citosina.
ARN → Formado por bases → Adenina y Guanina → Purinas
→ Uracilo y Citosina → Pirimidinas
Adenina siempre se empareja con Uracilo, mientras que Guanina se empareja con Citosina.

An example of how poaching affects biodiversity is selling baby gorillas at high prices.
Poaching is the illegal trade and killing of wild animals. Some of the animals and plants are sold as trophies and "folk medicines", others as pets and houseplants. The level of poaching cannot be overstated, as there are more tigers in captivity than in the wild. Killing wildlife is bad for biodiversity. Illegal hunting and trafficking of animals.
Poaching was once done by poor farmers to make a living and supplement their meager diet. He opposed the hunting privileges of nobles and monarchs.

how do palientologists classify fossils how does this compare to the way that biologists classify living animals
Scientists may be able to predict which species will become extinct by studying fossils. Fossils can be utilized to reconstruct pedigrees and identify family traits.
Scientists can use fossils to determine the time scale over which traits evolved. Scientists can utilize fossils to learn about the traits of ancient animals. Paleontologists compare the properties of species from different historical eras.
They use this information to try to understand how creatures evolved over millions of years Paleontologists classify fossils using physical characteristics that correspond to the Linnaeus system, and the organism then names the genus and species in Latin. A paleontologist collects as many fossils as possible from a rock or silt.

They require a long time to become exceptionally tall interminably. They give an overhang to conceal the others and give natural surroundings to many living with widely varied vegetation.
Notwithstanding trees, each progressive local area harbors numerous other living things, with the best variety populating the peak local area. Comparative biological zonings happen among marine widely varied vegetation, reliant upon such environmental variables as a base organization, accessibility of light, and level of saltiness.
Particular logging is a more environmentally maintainable practice than clear-cutting, which involves eliminating all trees simultaneously. The thought behind particular logging is to keep lopsided or all-matured timberland of trees fluctuating in age as well as in size and species also.

During the ejection period, _______.

Cardiac output is _______. equal to heart rate times (EDV minus ESV) equal to heart rate times stroke volume equal to blood flow equal to blood flow and equal to heart rate times stroke volume All of the above. Request Answer Part C The left side of the heart pumps blood _______. The left side of the heart pumps blood _______. to the lungs through the tricuspid valve and to the lungs through the tricuspid valve through the aortic valve Request Answer Part D What variable(s) can the cardiovascular system alter to maintain blood pressure
Answer:
A. Blood is pumped into the aorta and the pulmonary trunk.
B. All of the above.
C. Through the aortic valve.
D. Resistance, stroke volume and heart rate.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
In conclusion, the following can be deduced;
A. During the ejection period of the cardiac cycle, the mammalian heart pumps blood into the aorta and the pulmonary trunk.
B. Cardiac output can be defined as the volume of blood that is being pumped by the mammalian heart through the left and right ventricle per unit time (minute).
C. The left side of the mammalian heart in all living organism pumps blood through the aortic valve.
D. The variables the cardiovascular system can alter to maintain blood pressure include the following; resistance, stroke volume and heart rate.
