describe how the skin works when the place is very hot​

Answers

Answer:

when body temperature rises, such as when exercising on a hot day, the dermal blood vessels will dilate, in the sweat glands begin to secrete more sweat. the invaporation of the sweat from the surface of the skin cools the body by dissipating heat.

Explanation:

Hope this helped Mark BRAINLEST!!!

Answer:

When it is hot, we normally sweat. Sweating removes the heat energy from our skin. Our blood vessels open up which lets more blood flow. This allows a way for the heat to be lost. It lets your body cool down or try and cool down.

how are diffusion and endocytosis similar?

Answers

Endocytosis and exocytosis are similar in that they are both forms of cell transport. They differ because in endocytosis, a cell transports molecules into a cell (think: endo - in), and in exocytosis, the cell's molecules are transported by being expelled.

In the Hershey Chase experiment components of bacteriophages were labeled with radioactive isotopes of sulfur and phosphorus What was
the Hershey-Chase evperiment designed to determine?

Answers

Answer:

c

Explanation:

It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

What was  Hershey-Chase experiment?

The Hershey-Chase experiment, also known as the "Blender Experiment," was a classic experiment in molecular biology that was conducted in 1952 by Alfred Hershey and Martha Chase. It was designed to determine whether the genetic material of the bacteriophage (a type of virus that infects bacteria) is made of DNA or protein.

In the experiment, components of the bacteriophage were labeled with radioactive isotopes of sulfur and phosphorus. The labeled phages were then used to infect bacterial cells, and the cells were subjected to various treatments to separate the viral components from the bacterial components.

The results of the experiment showed that the genetic material of the bacteriophage was made of DNA, not protein. This was determined by the fact that the labeled DNA, but not the labeled protein, was able to enter the bacterial cells and infect them. This experiment provided strong evidence for the "central dogma" of molecular biology, which states that genetic information flows from DNA to protein, but not the other way around.

Which statement best explains how a light wave behaves when moving from air to water?A:it speeds up and bands B:it slows down and bands C:it speeds up and continues straight D:it slows down and continues straight.

Answers

Answer:

it speeds up and bends

Explanation:

common sense lol

The statement that best explains how a light wave behaves when moving from air to water is "it slows down and continues straight." That is the last option, i.e., option D, as light travels more slowly in water.

What is the significance of the waves at different mediums?

Waves react differently in different mediums, such as when the phenomenon of refraction is used in many optical devices such as lenses, prisms, and mirrors, and these devices change the property of light to slow down and bend when moving from one medium to another. In microscopes and telescopes, the study of light refraction has provided important insights.

Hence, the statement that best explains how a light wave behaves when moving from air to water is "it slows down and continues straight." That is the last option, i.e., option D, as light travels more slowly in water.

Which level of organization forms the fundamental base for all other levels
in the hierarchy of life? *
Cell

O Tissue
Organ
Organism

Answers

Answer:

organ

Explanation:

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

The biological level of organisation range from organelle to biosphere. Therefore, option (A) cell  forms the fundamental base.

What do you mean by hierarchy of life ?

Cells join to form tissues in larger animals, which are clusters of similar cells performing similar or related jobs. Organs are groups of tissues that work together to fulfill a certain task. Organs can be found in both plants and animals. An organ system is a more advanced level of organization made up of organs with similar functions. 

A population is the aggregate term for all members of a species that are present in a given location. An ecosystem is made up of all the living things that exist in a specific location as well as the abiotic, non-living elements of that environment, such as soil nitrogen or rainwater. The biosphere is a group of organisms that is organized at the highest degree possible.

Thus, option (A) cells forms the fundamental base for all other levels

Which statement best describes the chemical substances secreted by the endocrine glands?

Answers

Answer: B if its wrong so be it

Explanation:

Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds. Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase. The figure shows two circular models, labeled Model A and Model B, that represent the cell cycle of fruit flies after fertilization. Model A represents cell cycles 1 through 13, and it contains two phases. Model B represents cell cycles 14 through 16, and it contains three phases.
What of the following explains the advantage of a G2 phase during embryonic development?
A Cells can undergo the cell cycle more quickly with a G 2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase.
D Cells are able to produce two new daughter cells with a G2 phase.

Answers

Answer:

C. Cells are checked for DNA damage before entering mitosis with a G2 phase.

Explanation:

G2 phase is very important phase of cell division in which cells are checked for DNA damage before entering mitosis with a G2 phase as well as correct duplication of the DNA is also verified and cell proteins that are necessary for cell division are also produced. This phase comes after S stage in which replication of DNA occurs so this G2 phase check the damages before starting of mitosis.

Write a scientific explanation that explains how oxygen and carbon dioxide travel within the seed and the egg.

Answers

The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.

Please mark brainliest :)

Carbon dioxide and oxygen travel within the seed and egg to break the energy or food inside the seed or egg. It comprises schematic steps which are responsible for these functions.

What do you mean by Seed?

Seed may be defined as the unit of reproduction of a flowering plant, capable of developing into another such plant.

The oxygen enters the seed and gets absorbed by the seed coat. It makes the seed coat wet and soft due to oxygen absorption. This oxygen now combines with energy that is stored inside the seed. The level of carbon dioxide increases when the process of photosynthesis will be initiated.

Therefore, carbon dioxide and oxygen travel within the seed and egg to break the energy or food inside the seed or egg.
