Read the passage from Darwin's journal. sorry its so long


The Amblyrhynchus, a remarkable genus of , is confined to this archipelago; there are two species, resembling each other in general form, one being terrestrial and the other aquatic. This latter species (A. cristatus) was first characterized . . . from its short, broad head, and strong claws of equal length, that its habits of life would turn out very peculiar, and different from those of its nearest ally, the iguana. It is extremely common on all the islands throughout the group, and lives exclusively on the rocky sea-beaches, being never found . . . even ten yards in-shore. It is a hideous-looking creature of a dirty black colour, stupid, and sluggish in its movements. The usual length of a full-grown one is about a yard, but there are some even four feet long; a large one weighed twenty pounds: on the island of Albemarle, they seem to grow to a greater size than elsewhere. Their tails are flattened sideways, and all four feet partially webbed. They are occasionally seen some hundred yards from the shore, swimming about; and Captain Collnett, in his voyage says, “They go to sea in herds a-fishing, and sun themselves on the rocks; and may be called alligators in miniature.” It must not, however, be supposed that they live on fish. When in the water, this lizard swims with perfect ease and quickness, by a serpentine movement of its body and flattened tail—the legs being motionless and closely collapsed on its sides. A seaman on board sank one with a heavy weight attached to it, thinking thus to kill it directly, but when an hour afterwards, he drew up the line, it was quite active. Their limbs and strong claws are admirably adapted for crawling over the rugged and fissured masses of lava, which everywhere from the coast. In such situations, a group of six or seven of these hideous reptiles may oftentimes be seen on the black rocks, a few feet above the surf, basking in the sun with outstretched legs.

cause if they werent strong they would break if they tried to climb the rocks... also the first guy said webbed feet cause there is a VERY SIMILAR question that asked how they could swim... its in the screenshot of what he was answering

The structural adaptation does the cristatus lizard have to help them climb rocks is strong claws.

Explain your answer briefly?

If they were not strong they would break if they tried to climb the rocks. Also the first guy said webbed feet cause there is a very similar question that asked how they could swim.

Why xylem and phloem are called complex tissues? How are they different from one another?

Answers

Answer:

Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.

Explanation:

My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)

Answers

It decreased in frequency over time.

Trait B decreased in frequency over time. So, the correct option is A.

What is trait?

A trait is an attribute or characteristic of an organism that is influenced by its genes, according to genetics. Behavioural and physical characteristics, including intelligence and friendliness, can be altered by a combination of hereditary and environmental variables.

A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.

Hence, the correct option is A.

Jason joined a group that would work towards solving the workplace safety issues in his organization. Arrange Jason’s actions according to the stages of development of his group.

Answers

Answer:

- Jason asked his fellow group members  about their hobbies and interests .

- Jason and another member disagree on  what their respective roles should be in  the group.

- Jason resolved his differences with the  other group members .

- Jason began working with the group  members as a complete unit .

Explanation:

The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

Answers

Answer:

Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.
