Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.

What is genetics?Genetics has been known as the study of the heredity as well as the variation of the inherited the characters and the genetic properties and the organism's feature and the characteristics. It has been also known as the branch of biology that has to deal with the study of genetic variation, genes, and the heredity in the organisms.
The main function of the DNA has to carry the information from one generation to the another generation this has been the reason due to which DNA has been also known information molecule.
The main function of mRNA has to work as the immedieter between the protein and DNA which has been utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
Therefore, Some agents of mutation that can affect the genes of humans are ionizing radiation and codon errors as well as failure of repair by ligase.

The predominant plants found in the savanna are grasses, and there are only a few isolated or small clusters of trees. Which abiotic factor helps to maintain the savanna as a grassland rather than a forest?
A Loose Soil
B Abundant rainfall
C warm temperatures
D lightning Fires
PLEASE HELP
Loose soil is the abiotic factor which helps to maintain the savanna as a grassland rather than a forest. Thus, the correct option is A.
What are abiotic factors?Abiotic factors are those components of the ecosystem which are non-living. Abiotic factors include soil, temperature, rainfall, fire, etc.
Savanna is a biome which contain predominantly grasses with a few isolated or small clusters of trees in the ecosystem. The loose soil in this biome is mainly responsible for maintaining savanna as a grassland rather than a typical forest.
Loose soil is an abiotic factor which is responsible for the forestation of an ecosystem. It is difficult for the big trees to hold the loose soil whereas the grass have their perennating organs protected below the surface of the soil. Thus, they are favored in the savanna biome.
Therefore, the correct option is A.

Which types of plant cells must receive glucose from other plant cells?
Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
The type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.
Photosynthesis is a group of metabolic reactions by which plant cells generate simple carbohydrates (i.e., glucose) and oxygen by using the energy from the sun, carbon dioxide and water.In consequence, non-photosynthetic cells cannot produce glucose and thus need to receive this nutrient from photosynthetic cells.An example of non-photosynthetic cells is the root cells found underground.In conclusion, the type of plant cells that receives glucose from other plant cells are NON-PHOTOSYNTHETIC plant cells.

1. What do DNA Replication and Cell Division have in common?
2. Define Cell Differentiation in your own words.
3. Why are stem cells consjdered unique?
Answer:
1: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. This process is called chromosome segregation.
2: Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
3: Stem cells have unique abilities to self-renew and to recreate functional tissues. Stem cells have the ability to self-renew. Unlike muscle cells, blood cells, or nerve cells—which do not normally replicate— stem cells may replicate many times.

In a herd of beef cattle, the average yearling weight of all animals was 800 lb when corrected to a bull basis. Bulls and heifers kept for breeding weighed 1000 and 825 lb, respectively. The progeny of those individuals selected for breeding had an average yearling weight corrected to a bull basis of 845 lb. What is the apparent genetic control of the trait
Answer:
Explanation:
The trait is genetic and not dependent on environment. When a trait is dependent on the genetic component of the parental generation, the ability of the traits to be passed from a generation to another is high and this will be revealed in their resemblance with the parent. Hence, the case of the offspring with an average weight of 845lb.
If the trait is controlled or influence by the environment there will be a difference when the offspring is produce because until the same environment is given to the offspring the trait cannot be expressed.
