How does environment factor effect population growth?​

Answers

Answer:

Exponential growth assumes that environmental factors like food, water supply, space, shelter, disease organisms, predators, weather conditions, and natural disasters do not affect the birth or death rate. As long as birth rate exceeds death rate (even slightly) population size will increase exponentially.

The cell cycle occurs in which order?
A. G1, S, G2, Cytokinesis, Mitosis
B. G1, S, G2, Mitosis, Cytokinesis
C. S, G1, Mitosis, G2, Cytokinesis
D. S, G1, G2, Mitosis, Cytokinesis

Answers

Answer:

B. G1, S, G2, Mitosis, Cytokinesis

Explanation:

G1 is the first stage of the cell cycle, and it is essential for cell growth.

Next, the S (Synthesis) phase occurs. This phase involves DNA synthesis to prepare the cell for division.

G2 is the next phase, and it involves preparing and growing the cell for mitosis.

Mitosis is the next stage, where the cell divides into 2.

Lastly, Cytokinesis occurs after mitosis, and it creates the two daughter cells.

So, the correct answer is B. G1, S, G2, Mitosis, Cytokinesis

A projectile is fired vertically upward at an initial velocity of 100 m/s. How high will it rise? How long will it take to reach that height?

Answers

The question is solved using the equations of motion

According to the equations of motion:

[tex]v^2 = u^2 -2gh[/tex]

v = final velocity

u = initial velocity

g = acceleration due to gravity

h = height

Note that at the maximum height, the final velocity (v) = 0 m/s

so we can write:

[tex]u^2 = 2gh[/tex]

[tex]h = \frac{u^2}{2gh}[/tex][tex]h= \frac{100^2}{2 * 10}[/tex]

h = 500 m

The time taken is obtained from:

[tex]v= u - gt[/tex]

since v= 0 at maximum height

[tex]u = gt\\\\t= u/g\\\\t= 100/10\\t = 10 s[/tex]

Then, answer Part B.Caused by a mutation, sickle cell anemia is a disorder that affects hemoglobin, the red blood cell molecule that carries oxygen to cells throughout the body. The β chain of the hemoglobin protein is a single chain of amino acids and is 147 amino acids long. In humans, the gene that encodes for the β chain is located on chromosome 11. The diagrams show the DNA, RNA, and amino acid sequence of an unaffected person and a person with sickle cell anemia.image f8707eaefc0147c9bd074a15bb19c344Part A:Where does the mutation that causes this disorder occur?AThe mutation occurs on the DNA.BThe mutation occurs on the RNA.CThe mutation occurs on the ribosomes.DThe mutation occurs on the amino acid.Part B:Which BEST describes the result of this mutation?AThe entire sequence of amino acids is changed.BThe RNA strand does not code for the correct amino acids.CThe change in amino acids shortens the polypeptide sequence.DThe alternation of a single nucleotide encodes for a different amino acid.

Answers


Sickle cell disease is a hereditary disease seen most often among people of African ancestry. Caused by mutations in one of the genes that encode the hemoglobin protein, the disease is inherited as an autosomal recessive trait. The mutation causes the red blood cells to take on an unusual sickle shape. Individuals affected by sickle cell disease are chronically anemic and experience significant damage to their heart, lungs, and kidneys.

Answer:

D. Supporting

Explanation:

Ecosystem services include provisioning, regulating, culture and supporting services.

Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.

Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.

A plant does not grow when its apical meristem is cut. justify the statement​

Answers

Answer:

Apical Meristem undergo rapid cell division ,hence is responsible for growth in height of the plant and is found on the tip of the plant. So, if apical meristem is either damaged or cut, growth can't take place and the plant will stop growing

Explanation:

Apical meristem undergo through rapid cell division, thus it is responsible for growth of height and if the meristem is cut the growth stops.

What is apical meristem?

Apical meristem is defined as the region of cells responsible for the division and growth in the root and shoot tips in plants.

Apical meristems are special zones of growth present at the tips of plants and these are responsible for the growth of shoots and roots and shows primary plant body.

The main function of apical meristem is growth of plant and unlike undifferentiated plant cells, differentiated plant cells generally cannot divide and produce different types of cells.

There are mainly two types of apical meristem and these are shoot apical meristem (SAM) and root apical meristem ( RAM).

Therefore,Apical meristem undergo through rapid cell division, thus it is responsible for growth of height and if the meristem is cut the growth stops.

A water strider (which can walk on water)has legs that are coated with a hydrophobic substance. What might be the benefit? What would happen if the substance were hydrophilic?

Answers

Answer:

The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.  

The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.

How are surface waves different from body waves? Which are more damaging?

Answers

Answer:

Explanation:

surface waves decay more slowly with distance than body waves, which travel in three dimensions. Particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage.

Answer:

surface waves decay more slowly with distance than body waves, which travel in three dimensions. The particle motion of surface waves is larger than that of body waves, so surface waves tend to cause more damage. Surface waves. Their side-to-side motion (like a snake wriggling) causes the ground to twist from side to side, that's why Love waves cause the most damage to structures. Rayleigh waves create a rolling, up, and down motion with an elliptical and retrograde particle motion confined to the vertical plane in the direction of propagation.

What characteristic of sexual reproduction did Mendel investigate that resulted in offspring expressing characteristics that differed from their parents?

Answers

Explanation:

Mendel crossed two unlike parents to get offspring with characterestics that differ that of the parents

Mendel used the characteristic of sexual reproduction in which the genes from the two parents combine to form the offspring. This results in offspring expressing the characteristics that differed from their parents.

What is Sexual reproduction?

Sexual reproduction is a type of reproduction in which the production of new organisms occur by the combination of genetic information of the two parents or individuals of different sexes. In most of the species, the genetic information is carried on the chromosomes in the nucleus of reproductive cells called gametes, which fuse to form a diploid zygote in the organism which matures to form a complete organism.

Mendel called the material which is responsible for the characteristics as "factors", and he proposed that during sexual reproduction, each of the parent contributed a form of this factor to the resulting offspring. This combination of the parental factors then determined which form of a trait will be visible in the offspring.

Answer:

The correct answer is - The axial skeleton is like the frame of a swing set; the appendicular skeleton is like the swings.

Explanation:

The axial skeleton is the part of the human skeleton system that supports and protects vital organs of the body and makes a frame for the body structure that include bones of skull, trunk rib cage and ribs. The axial skeleton system is like a frame of a swing set that holds the swings and provide support to the swings.

On the other hand, The appendicular skeleton is like the swings of the of the swing set that can move and provide motion to the body, upper body limb, shoulder girdle and lower limb and pelvic girdle are the bones of appendicular skeleton.

Thus, the correct answer is - The axial skeleton is like the frame of a swing set; the appendicular skeleton is like the swings.
