Based on the direction of the blood flow, through what type of blood vessel is blood flowing in the diagram? #19

Answer:

1. F

2.T

3.F

Explanation:

Answer: 1. Mitosis

2. Answer A.

Explanation:

Stick insects that reproduce asexually are less biologically diverse because they can't evolve as quickly as species that reproduce sexually can. Thus, option A is correct.

Asexual reproduction, in contrast to sexual reproduction, only contributes to genetic variety in the population if a chance mutation in the organism's DNA is passed on to the progeny.

Evolution can occur gradually. Asexual creatures often evolve relatively quickly following a dramatic mutation and do not need as many generations to accumulate adaptations as do populations that reproduce sexually.

Asexual reproduction has the benefit of allowing for rapid population growth under the right circumstances. You only require one parent. Since you don't require a partner, it is more time and energy efficient.

Therefore, new organisms are usually genetically identical to the parent.

Exposition is a text that elaborates the writer‘s idea about the phenomenon surrounding. Its social function is to persuade the reader that the idea is important matter.

Explanation:

Answer:

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase).

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope ...

Answer:

A) Evolution occurred because the allele frequency changed over time.

C) The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

E) The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

Explanation:

Based on the data, you can conclude:

Evolution occurred because the allele frequency changed over time.

The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.

The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.

The possible conclusions that can be drawn are

The mutation is a change in the DNA sequence that results from the copying mistakes that tke place during the cell division and the exposure to the radiating agent, exposure to virus and chemicals also leads to the cases of gene mutation.

2) an ocean trench

Explanation:

Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.

Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.

Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.

Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Enzymes work by speeding up chemical reactions through the lowering of the activation energy of the reactants.

In every reaction, reactants need to summon a minimum energy amount before they can get to products. this energy is referred to as activation energy.

When an enzyme is introduced into a reaction, it lowers the activation energy. By doing so, reactants can get to products quicker because the mountain they need to climb has been lowered by the enzyme.

In other words, enzymes create a shorter route for reactants to take towards their destination - products.
