Answers

Answer: 3d illustration depicting cell division, a process whereby a cell divides into two new daughter cells with the same genetic material.

Explanation:

When you feel cold, there are sensors in your skin that tell the brain you need to warm up. The brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. The movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. Which characteristic(s) of life is being represented during this action?
A) respond to stimuli
B) maintain homeostasis
C) growth and adaptation
D) respond to stimuli and maintain homeostasis

Answers

I think it is D because your responding to the cold from stimuli and by creating heat to keep your body the average temperature it is homeostasis.

how do you find per capita growth rate over a month?​

Answers

All you have to do is take the CGR (capita growth rate) percentage you just found and divide it by the number of years, months, etc. The complete formula for annual per capita growth rate is: ((G / N) * 100) / t, where t is the number of years.

In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM​

Answers

Answer:

The Thermosphere

Explanation:

Just took the test on A P E X, it's right. Hope this helps :)

Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.

What are the different layers of the atmosphere?

The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.

In the troposphere, the temperature rises from bottom to top.  The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.

The atmospheric layers protect the life on Earth.

Carbon one is single bonded to two hydrogens, and a side chain. The side chain is oxygen single bonded to carbon. The carbon is double bonded to oxygen and an R 1 side chain. Carbon two of the core chain is single bonded 1 hydrogen and to oxygen which is single bonded to carbon. The carbon is double bonded to oxygen and single bonded to an R 2 side chain. Carbon three is single bonded to two hydrogens and a phosphate group. P O 4 2 minus. Phosphatidate (phosphatidic acid) Identify the lipids that have phosphatidate as a precursor.

Answers

Answer:

glycerolphospholipids, triacylglycerol, and cardoilpin.

Explanation:

PS: Kindly check the attached picture for the structure of Phosphatidate (phosphatidic acid).

The chemical compound known as Phosphatidate or the phosphatidic acid belongs to a group known as phospholipids. Phosphatidate or the phosphatidic acid can be prepared by using the chemical compound known as diacylglycerol kinase to phosphorylate diacylglycerol. Also, Phosphatidate (phosphatidic acid) can be prepared by making use of lysoPA-acyltransferase to acrylate lysophosphatidic acid[a phoshopipid derivative].

The lipids that have Phosphatidate (phosphatidic acid) as precursor are glycerolphospholipids, triacylglycerol, cardoilpin, phosphatidylinositol

A. Condensation of DNA

B. Crossing over

C. Pairing of chromosomes

D. Spindle formation

Answers

The. Answer I believe is c

All of the following events occur during prophase in mitosis except crossing over (Option B)

Mitosis can be divided into four phases: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatids condense into chromosomes, thereby making them visible.

The mitotic spindle is a structure composed of microtubule proteins that segregate the chromosomes in mitosis. This structure is formed in prophase.

In Prophase homologous pairs of chromosomes are paired together. In metaphase, these chromosomes are lined up at the equator of the cell and sister chromatids are attached to the spindle fiber.

Crossing over (or recombination) is the exchange of genetic material between non-sister chromatids that occurs during prophase I of meiosis.

In conclusion, condensation of DNA, the pairing of chromosomes and, spindle formation occur during prophase, whereas crossing over occurs in prophase I of meiotic cell division (Option B).

How does the water on earth regulate the earth temperature

Answers

Answer:

It absorbs a lot of the sun’s energy.

Explanation:

A large portion of the sun’s energy and heat is absorbed by the oceans, which causes water to evaporate. Water has a high heat capacity, and therefore absorbs a large portion of the sun’s heat, regulating the earth’s temperature.

A. The cells will immediately enter death phase

B. The cells will enter lag phase

C.The slope of the exponential phase will become shallower

D. The slope of the exponential phase will become more steep

Which one is the best answer ? Choose only one answer

Answers

Answer:

B. The cells will enter lag phase

Explanation:

There are four identifiable phases of bacterial growth in a culture. These are: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.

The lag phase occurs when there is need for the growing bacterial cells to adapt to new conditions.  The adaptation period, i a time when the cells  adjust themselves to the new conditions. The length of the lag phase varies considerably, depending on the initial and final conditions of  the bacteria cells.

Hence, when the temperature is slightly lowered below the optimum halfway into the exponential phase, the cells will enter into lag phase

DNA undergoes the process of replication to produce new strands of identical DNA before cell divisions. Describe the basic dna replication. I will give you brainliest

Answers

Answer:

Please mark as Brainliest

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication

Step 1 Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be unzipped into two single strands

Step 2 Primer Binding. The leading strand is the simplest to replicate

Step 3 Elongation

Step 4 Termination

Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being dominant. If true breeding red, long radishes are crossed with true breeding white, oval radishes, what will the offspring look like?

Answers

Answer:

The offspring will be purple and long

Explanation:

Radish flowers = Red, purple, or yellow

For a cross between a red-flowered plant and a white-flowered plant to yield all-purple offspring, that means either the red or white is dominant and the other recessive.

When cross it will result in 16 progenies.

How does the movement of water, carbon, and nitrogen in ecosystems differ from the movement of energy?

Please help me this is due today, thank you if you do^^

Answers

Answer:

While water, carbon, and nitrogen cycle through the ecosystem, energy flows through an ecosystem.

Explanation:

There is a limited amount of water, carbon, and nitrogen in an ecosystem, and therefore, it cycles and passes through an ecosystem multiple times. In the case of energy, however, it is different. Energy goes into a system, flows from organism to organism, and then leaves the system. For example, with water, that water will rain, gather in a river or body of water, and evaporate, doing the cycle over and over again. Energy from the sun however, gets collected by producers, then flows to the organism that eats the plant, then flows to the organism that eats that organism, and so on. The energy does not return to the sun, it just leaves the system (like for example when an organism dies).
