Which group of algae is responsible for formation of kelp beds along the North American coasts? Brown algae Green algae Red algae

Answers

The group of algae that is responsible for formation of kelp beds along the North American coasts is brown algae.
The correct answer is Brown algae. Brown algae is a group of algae is responsible for the formation of kelp beds along the North American coasts. This kind of algae is a large group that can be found in marine habitats, including seaweeds.

During glycolysis, the steps between glucose and formation of the triose phosphates collectively a. consume two ATP and two NADH molecules b. produce two ATP and two NAD+ molecules c. consume two ATP molecules d. produce two ADP and two NADH molecules e. consume two NAD+ molecules

Answers

Answer:

The correct answer is c. consume two ATP molecule

Explanation:

Glycolysis is the process in which glucose is partially breakdown into two pyruvate molecules. Glycolysis is divided into two-phase the first phase is the preparatory phase and the second phase is the payoff phase.

In preparatory phase energy is consumed and the formation of two molecules of glyceraldehyde 3 phosphate(triose phosphate) takes place with the consumption of two ATP, therefore, this phase is called energy investment phase.

These two ATP are consumed when fructose 6 phosphate converts into fructose 1,6 bis-phosphate. Therefore, the right answer is c.

A 22-year-old man had a strong acid chemical splashed into both of his eyes. he is conscious and alert, is experiencing intense pain, and states that he is wearing contact lenses. treatment should include:

Answers

The treatment should include removing thecontact lenses and begin irrigating the eyes by introducing the flushing fluidat the inner corner of the eye close to the nose and allowing it to run acrossthe eye to the outer edge. The flushing fluid washes the eye and helps torelieve irritation, discomfort, burning and itching by removing the strong acidchemical.





Different modes of primate locomotion (7) encompass: a) Bipedalism, quadrupedalism, brachiation, leaping, galloping, swimming, flying b) Crawling, sliding, gliding, hopping, swinging, scuttling, slithering c) Walking, running, hopping, climbing, flying, swimming, burrowing d) Trotting, jumping, floating, wading, rolling, slinking, hopping

Answers

Final answer:

Primates, including humans, have different modes of locomotion such as bipedalism and brachiation due to specific morphological adaptations. These changes have been hypothesized to have evolved from our arboreal ancestors. Each primate subgroup, from lemurs to humans, has adapted in different ways to their environment.

Explanation:

Different modes of primate locomotion includes a series of movements like bipedalism, quadrupedalism, brachiation (swinging from branch to branch), leaping, and more. These locomotion modes are possible due to several morphological adaptations such as a rotating shoulder joint and thumbs and big toe widely separated from other digits, which allow for gripping branches. For instance, in bipedal locomotion, one leg is on the ground (stance leg) and the other is in the air (step leg) striding forward.

All primate species are believed to have descended from arboreal ancestors hence the adaptations for climbing trees. However, not all primate species today are arboreal. Large brains, stereoscopic vision, and a flattened nail instead of claws are among the specific characteristics of primates, especially those adapted to arboreal life.

Interestingly, humans are part of the primate order, which also includes lemurs, monkeys, and apes. These primate groups possess the necessary physical adaptations for different modes of locomotion, which allow them to live in diverse environments from tropical forests to savannahs.

Where does gas exchange take place in the respiratory system, and between what structures?

Answers

The gas exchange take place in the lungs where carbon dioxide and oxygen diffuse across alveoli (which are attached to every bronchial tubes) and tiny capillaries surrounding them.

Final answer:

Gas exchange in the respiratory system occurs in the alveoli, which are small air sacs located in the lungs. Oxygen diffuses from the alveoli to the capillaries, while carbon dioxide diffuses from the capillaries to the alveoli.

Explanation:

Gas exchange in the respiratory system takes place in the alveoli, which are small air sacs located at the ends of the respiratory bronchioles. These structures are found within the lungs. The alveoli are surrounded by capillaries, which are tiny blood vessels.

When we breathe in, oxygen from the air enters the alveoli and diffuses across the thin walls of the alveoli and capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be removed when we exhale.

So, the gas exchange occurs between the alveoli and the capillaries surrounding them.
