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.
What structural adaptation does the A. cristatus lizard have to help them climb rocks?
Awnsers:
A.strong claws
B.black color
C.flattened tail
D.webbed feet
Answers
Answer:
A) strong claws
Explanation:
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.

Answers
Answer: C
Explanation:
Ligaments are strips of tough tissues that serves as connective tissue for two or more bones and cartilages. These also holds the joints together.
Ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.
What is the significance of the ligament?Ligaments are significant for many different factors, such as that they have an important role in physical activities such as sports and maintain optimal performance and injury prevention as they have a rich blood supply. They have an important role in preventing injuries to joints and bones as they protect bones and cartilage from excessive stress and connect bones to bones.
Hence, ligaments are strips of tough tissue that connect bones to bones; that is the third option because the bones that are present in the body are connected to each other with the help of the ligaments.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answers
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.
Answers
Answer:
There are many reasons to get an influenza (flu) vaccine each year.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy.
Flu vaccine can be life-saving in children.
Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
Explanation:
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.
What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."Hence, in order to reduce the disease caused by flu, it is recommended to receive a vaccine.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green
algae-living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its
photosynthetic activity from Elysia chlorotica, the sea slug that's considered to be a photosynthesizing animal?
CA In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only
during the immature juvenile stage of the slugs life cycle.
OC Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from
algae into its cells.
D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a
photosynthesizing organism only when it requires food.
Answers
Answer:
The correct answer is option C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Explanation:
Elysia chlorotica is an animal of the mollusk member that is known as the animal that can make its own food in unfavorable conditions. Elysia chlorotica search out plants and they eat them. They assuredly don't photosynthesize n its own.
They take the mechanism that permits plants to collect sunlight based vitality. The slugs take up these smaller than normal machines, called chloroplasts, into their skin, which turns them emerald green.

3.) because the long dna will fit inside the cell.
4.) because the dna needs to attach itself to support .
Answers
Answer:
3.) because the long dna will not fit inside the cell.
Explanation:
This question is oddly written. At first glance, I can tell it's not 1 or 2 because DNA doesn't "dissolve" in cell "water", nor will it "down" (I'm assuming this means "drown"?).
The main reasons for DNA packaging are so that the DNA can fit into the cell, and so it's protected from damage. The DNA is vital to the cell, so it protects it by coiling it up. Coiling and packaging are also important when it comes to gene expression.

Answer and explanation: it would mean that there would be an increase of fish which is what seaguls eat but a decrease of, for example, leopard seals because if there aren't enough seagulls the leopard seals would die of starvation which would then again decrease another animal species because there aren't enough leopard seals. This would then repeat itself again and again.
