Answer:

The correct answer will be- homologous structures

Explanation:

The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.

Studying the anatomical features of the organisms and the collected specimens (fossils) shows that some organisms posses similar anatomical structures which could be performing different functions.

The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures. "

Thus, homologous structures are the correct answer.

describe the role of deep fascia in compartmentalizing the segments of the limbs (i.e., arm, forearm, thigh, leg).
Brilliant_brown [7]

The role of deep fascia in compartmentalizing the segments of the limbs is to transmits the load between bones and intermuscular septa.

These compartment are known as osteofascial compartment, these compartment forms by the fascia that enables the means of containing and separating the groups of muscles into relatively well defined spaces that are compartment.

The deep fascia helps to support and protect muscles and other soft tissue structure. Also it provide a barrier against the infection from one skin to another. The fascia is a structure of connective tissue that surrounds muscles, groups of vessels and nerves.

A population of a tree snail species has different patterns in their shells. These slight
Alja [10]

Variations can be genetic or environmental, the traits are passed from one generation to other generation of snail is from from both parents to offspring and through the environment.

The correct answer is C.

Explanation:

Genetic variation in an organism is passed to the offspring by its parents.

environmental variation is the the result of different environment with which individual adapt.

Natural selection is a process in which a suitable trait which is well adapted to the environment is passed on tho future generations.

Genetic variation is the change in DNA or gene of the individual trait. The tree snails having different pattern in their shells is due to the habitat they are living in.

The snails which have well adapted to the environment are able to reproduce and pass on the traits to their progeny. The variation is due to the traits passed from parents through the environment also.

Family programmes help to reduce the rates of poverty, over population etc.

<h3><u>Explanation:</u></h3>

Family programming is a scientific approach to initiate a control over the reproduction of eligible couples in a particular population. Family plannings are initiated by the government as well as should be adopted by the couples in order to maintain a very healthy relationship as well a healthy population.

Family planning helps to reduce the poverty, hunger, epidemics, sexually transmitted diseases like AIDS etc and improves the maternal health, infant health, reduces maternal mortality rates, infant mortality rate, neonatal mortality rate etc. This uses the basic contraceptive methods as well as different other factors like when to take a baby and all.

Describe the main molecule found in nucleus and explain how it controls the cells functioning​
SCORPION-xisa [38]

The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

Arrange the order of events for the internalization of LDL particles into cells:
ElenaW [278]

Answer:

The correct answer is "5-1-3-2-4".

Explanation:

Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:

5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.

1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.

3) Several endocytotic vesicles fuse to form an endosome.

2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.

4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
