Answer:State how the phylum Chordata differs from other animal phyla. Compare and contrast invertebrates and vertebrates.

Explanation:

Animal. What type? Now that is a good question. This azure vase sponge is an animal, but how is it classified? It is estimated that there are easily over a million species of animals on Earth. How are all these species divided into their various classifications?

Classification of Animals

All animals share basic traits. But animals also show a lot of diversity. They range from simple sponges to complex humans.

Major Animal Phyla

Members of the animal kingdom are divided into more than 30 phyla. Table below lists the nine phyla with the greatest number of species. Each of the animal phyla listed in the table has at least 10,000 species.

Imagine an animal cell lost half of its mitochondria. Explain how the cell would be different.
seropon [69]

Answer:

Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...

Explanation:

Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.

in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

i hope this is helpful

have a grest day!!:))

In a motor reflex , such as the patellar tendon reflex, afferent action back to the spinal cord is mediated through which of the
brilliants [131]

Answer:

The correct answer will be option-B.

Explanation:

The patellar tendon reflex is the kicking movement of the lower leg in response to the tap on patellar cap used to test the L2, L3, and L4 segments of the spinal cord in the body.

The spinal cord interacts with muscles through muscle sensors called muscle spindle which signals after the stretching of the muscle. The signals are sent to the spinal cord through afferent neurons or sensory neurons which starts the reflex action to prevent overstretching of the muscle.

Thus, Option-B is the correct answer.

vladimir1956 [14]

Answer:

Cognitive-behavioral therapy

Explanation:

Cognitive-behavioural therapy can be described as a very common type of psychotherapy which psychologists use to help patients undergoing anxiety disorders. It is a type of talk therapy. This kind of therapy trains your brain to become aware whenever you are thinking in a negative manner. It trains you to think in a positive manner instead. It helps a person to change the way they feel. Hence, cognitive-behavioural therapy is the best plan for patients with social- anxiety disorder.
