Which butterfly-shaped portion of the brain is responsible for spinal reflexes?

Answer:

Found in plant cell walls

Chitin is all of the following except it is found in the plant cell wall. So, the correct option is D.

It is the outermost layer of a cell that can be tough, flexible, and sometimes rigid. Its function is to provide structural support and protection to the complete cell.

The Cell-wall of fungi is made up of chitin. It is composed of N-acetylglucosamine subunits. It is also composed of linear fibrils like cellulose. Mostly, found in insect and crustacean shells.

Therefore, Chitin is all of the following except it is found in the plant cell wall.

A positive feedback loop that affects climate is change as the number of plants increases, the amount of CO2 decreases.

Scientists agree that one of the most effective ways to absorb part of the CO2 from the atmosphere would be to plant more trees, as they use CO2 to grow and release oxygen, this action brings benefits to the entire environment.

With this information, we can conclude that A positive feedback loop that affects climate is change as the number of plants increases, the amount of CO2 decreases.

Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.

The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.

The lens is normally clear and is located behind the iris. The pupil directs light to the lens.

Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.

Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.

The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).

Thus, eye lens helps to focus the object.

Crabs, pilchards, blennies and snappers are the examples of secondary consumers.

Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.

They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.

The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.

The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.

The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.

RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.

I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.  

Explanation:

Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".

The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.

Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

Answer: Narwhals, polar bears, and walruses will be affected the most.

Explanation:

Polar bears: The Arctic is warming about twice as fast as the global average, causing the ice that polar bears depend on to melt away. Loss of sea ice also threatens the bear's main prey, seals, which need the ice to raise their young.

Narwhals: The Narwhal's Arctic habitat is highly sensitive to climatic changes that result in increased atmospheric and ocean water temperatures. The Narwhal's annual migration from the north in summer to more southerly overwintering habitats exposes them to sea ice which is constantly expanding and receding. Because of the sea ice rapidly decreasing, narwhals could be exposed to new threats and noises.

Walruses: Habitat loss will be exacerbated for walruses by additional climate-change related factors such as ocean acidification, increased shipping and increasing development in the North, including oil and gas extraction, as well as increased disease and contaminant risks. biggest threat facing walruses is the loss of stable sea ice due to climate change. As a result of less sea ice, walrus are changing their behavior. Walruses feed on the ocean floor in the relatively shallow waters of the continental shelf, where the sea ice itself sustains a rich food web.

3. Chromosome

4. Genome

Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

Chromosomes are the thread-like structure made up of protein (histones) and a single molecule of DNA which carries all the genetic information in it. It is located in nucleus.

Human have 23 pairs of chromosomes including pairs of 22 chromosomes (i.e. Autosomal Chromosomes) and 1 pair of Sex Chromosome (XX or XY).

Each pair contain two Chromosomes inheriting from the parents, half from mother and another half from the father.

Each chromosome have a point which is constricted in the middle known as Centromere, which divides chromosomes into two arms i.e. short arm “p” and long arm “q”.

Thus, Nucleotide, Gene, Chromosome and Genome is the levels of genetic information in order from smallest to largest.

The homologous structure to the forearm of humans is the leg of the horse.

Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.

The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.

Homologous organs have different functions in organisms.
