Water molecules are sufficiently small that they do not require specific transporters to cross biological membranes. But because they are polar, diffusion of these molecules across the phospholipid bilayer is slow. Peter Agre won the 2003 Nobel Prize in Chemistry for his discovery that the rapid movement of water into and out of cells occurs via:________.

What enzyme connects the new bases to the old bases.

Answers

Answer:

Ligase is the enzyme that binds the new bases in the DNA template to the old bases. Explanation: The ligase enzyme performs a vital function in the replication and repair of DNA. It joins Okazaki fragments, seals DNA repairs, and seals recombination fragments.

There are free nucleotides present around the replication fork and DNA polymerase enzyme connects them to the old (template) strand using the complementary base pairing (A+T, C+G). Hydrogen bonds are again created between the complementary bases and new DNA strands rewind to form a double helix.

Identify and construct an explanation of the main disadvantage of growing a potato crop with few variations. What could be an unwanted effect?

Answers

The main disadvantage of growing a potato crop with few variations may be the loss of yield in a changing environment. It is a consequence of artificial selection.

What is artificial selection?

Artificial selection refers to the mating process made for humans in order to select crops and animals' progeny with desired traits.

The main subject of concern in artificial selection is the loss of valuable genetic variability.

In this case, artificial selection may lead to the potato crops being unresponsive to challenging environments.

how to calculate the concentration of starch in a solution

Answers

Use a measuring cup maybe?

Answer:

From the linear regression analysis of y=4.8811x+0.1453 we calculate the starch concentration by rearranging the formula to x=(y- 0.1453)/4.8811.

Explanation:

The starch concentration of the sample is 0.159 mg/mL. The dilution factor was 1:10 making it a concentration of 1.59 mg/mL. For each cuvette concentration calculation, multiply the concentration of the diluted starch solution in the Erlenmeyer flask by the volume of the diluted starch solution you added to the cuvette. Then, divide by the total volume of liquid you placed in the cuvette, which is 5 mL.

why are dolphins and whales called mammals even they swim like fishes​

Answers

Answer:

Both Whales and Dolphins are classified as mammals since they produce milk to feed to their young. Unlike other creatures in the sea, they also have warm blood, not cold.

Answer:

They are not fish, they are cetaceans! Unlike fish, they don't have gills, they are viviparous, which means they don't lay eggs and they produce milk for their babies. Also, they are warm-blooded.

How does the body react to cold temperatures?
A.Your body shivers to help it maintain homeostasis.
B.Your body shivers to make the internal temperature balanced with the external environment.
C.ou body sweats to make the internal temperature balanced with the external environment.
D. Your body sweats to help it maintain homeostasis.

Answers

Answer:

Your body shivers to help it maintain homeostasis.

Explanation:

This answer is 100% correct

Body react to cold temperatures Your body shivers to help it maintain homeostasis.

The correct option is A

When exposed to cold temperatures, the body responds through various physiological mechanisms to maintain its core temperature and achieve homeostasis. Shivering is one of the body's natural responses to cold temperatures. Shivering is an involuntary muscle contraction and relaxation that generates heat, helping to warm the body.

When the external environment is colder than the body's internal temperature, shivering helps to increase heat production by the muscles, which helps to counteract the heat loss to the surrounding environment. This is an essential adaptive response to prevent the body from cooling too much and to maintain a stable internal temperature within a narrow range necessary for proper physiological functioning.

Hence , A is the correct option

The tomato you examine in the lab develops from what structure in an angiosperm?.

Answers

Answer: The flower

Explanation: Angiosperms, or flowering plants, exist in many forms such as orchids, apple trees, and even tomatoes. The flowers act as pollination stations, which attract bees and bugs, and other pollinators to fertilize the flower. Once fertilized, it begins to develop into a fruit. This is why you will see cherry blossoms, apple tree blossoms, and a multitude of other flowering plants and trees producing fruit.

Answers

The neuronal cells that are short-lived and are frequently replaced are called the olfactory sensory receptors.

Neuronal cell regeneration

Neuronal cells, which is also called neurons, are the cells of the nervous system that aid in the transmission of electrical information from one cell to another.

Olfactory sensory neurons are bipolar nerves that are activated when airborne molecules in inspired air bind to olfactory receptors expressed on their cilia.

They are usually short-lived and are regenerated because they are constantly exposed to environmental agents.

Therefore, neuronal cells that are short-lived and are frequently replaced are called the olfactory sensory receptors.
