why do we have so much dna?
Answer:
Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome – the entirety of our genetic material. It is remarkable that each of the over 200 cell types in the body interprets this identical information very differently in order to perform the functions necessary to keep us alive. This demonstrates that we need to look beyond the sequence of DNA itself in order to understand how an organism and its cells function.

Intraspecific direct:
all the gray wolves feed on the same type of preytwo male deers fight over a mateInterspecific, indirect:
A robin and a blue jay try to eat the same wormthe rise in one species of bird limits the nesting space for other speciesTypes of competitionCompetition is a type of interaction in which two or more organisms of the same or different species compete over common limited resources.
When the competition involves organisms of the same species, the competition is said to be direct or intraspecific.
On the other hand, if the competition for resources involves organisms of different species, the competition is said to be indirect or interspecific.
Thus, all gray wolves feeding on the same type of prey and two male deers fighting over a mate are examples of direct or intraspecific competition. In the same vein, a robin and a blue jay trying to eat the same worm and the rise in one species of bird limiting the nesting space for other species are examples of indirect or interspecific competition.

Why DNA is absent in blood plasma?
Answer:
Why do blood cells not have DNA?
Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNA, and consequently cannot divide and have limited repair capabilities. The inability to carry out protein synthesis means that no virus can evolve to target mammalian red blood cells.
Explanation:
Blood plasma is a light amber-coloured liquid component of blood in which blood cells are absent but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume) and contains important dissolved proteins, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders.
Blood plasma is separated from the blood by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is then poured or drawn off. For point-of-care testing applications, plasma can be extracted from whole blood via filtration or via agglutination to allow for rapid testing of specific biomarkers. Blood plasma has a density of approximately 1,025 kg/m3 (1.025 g/ml).
Blood serum is blood plasma without clotting factors.
Plasmapheresis is a medical therapy that involves blood plasma extraction, treatment, and reintegration.
Fresh frozen plasma is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system. It is of critical importance in the treatment of many types of trauma that result in blood loss and is therefore kept stocked universally in all medical facilities capable of treating trauma.

The dense needles of Douglas fir trees can
prevent most light from reaching the forest
floor. This situation would have an immediate
effect on ?
The dense needle of Douglas fir trees preventing light from reaching the forest floor will have an immediate effect on the understory producers.
What are producers?Producers are green plants that are capable of utilizing solar radiation to fix carbon dioxide into carbohydrates.
A forest contains several layers of trees and may or may not have a herbaceous cover of herbaceous plants.
If the tree layers permit light to reach the floor of the forest, herbaceous ground cover may thrive. Otherwise, only a few, shade-tolerant herbs will grow on the ground layer.
In other words, if the dense needles of Douglas fir trees prevent most light from reaching the forest floor, it will have an immediate implication on the herbaceous ground cover of the forest.

Why are the components of the electron transport chain embedded in the inner mitochondrial membrane rather than floating freely in the cytoplasm of mitochondrial matrix?.
Answer:
To generate and maintain the proton gradient essential for ATP production.
Explanation:
ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.

Select the statements that correctly describe how a new DNA molecule reflects the original DNA molecule from which it was copied. Select the TWO answers that are correct.

b. The nitrogenous bases in the new DNA molecule are A, T, G, and C, but the original molecule contains A, U, G, and C.
c. Each new DNA molecule contains an original strand and a newly synthesized strand.
d. The two DNA molecules are exact opposites of each other according to base pairs.
e. Base pairing rules duplicate the base pairs of the original molecule in the new molecule.
Answer:
a. DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original
c. Each new DNA molecule contains an original strand and a newly synthesized strand.
Explanation:
DNA replication is an important process every cell must undergo prior to division. DNA replication is the process whereby DNA content is doubled. It occurs as a result of an enzyme called DNA polymerase, which synthesizes nucleotides.
DNA replication follows the semi-conservative model which uses one original DNA strand to synthesize a new DNA strand. The double-stranded DNA is separated into two single strands which serve as template for new strands. Due to the action of DNA polymerase, DNA replication proceeds in a 5' to 3' direction in the new DNA molecule and in the opposite direction in the original.
Also, each newly synthesized DNA molecule which is similar to one another contains an original strand (template) and a newly synthesized strand.
