If you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal

Answers

Answer:

Has more offspring that have the ability to survive and reproduce themselves.

Explanation:

Evolution fitness can be defined as a characteristic or quality possessed by living organisms and determines their adaptability, as well as level of success in terms of reproduction i.e giving birth to offsprings.

Hence, if you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal has more offspring that have the ability to survive and reproduce themselves.

Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.

Are claims about the effects of meditation most likely scientific or pseudoscientific?

scientific, because people have been claiming for thousands of years that meditation helps them
scientific, because observations of brain growth and chemicals are made carefully and repeatedly
pseudoscientific, because practices that are related to religion are based on beliefs and are subjective
pseudoscientific, because people have made claims about it but scientific observations have not been made

Answer:

M

Explanation:

Mitosis is a type of cell division that involves the production of two daughter cells that are genetically identical to one another. Mitosis encompasses two stages namely: Interphase and Mitotic phase. The interphase which further consists of G1, S, and G2 phases, is a preparatory phase for the cell to grow and replicate its DNA.

However, the separation of the sister chromatids (replicated chromosomes) into two daughter nuclei occurs in the Mitotic or M phase. Note that the M phase comprises of stages that includes: prophase, metaphase, anaphase and telophase.

Answers

Answer:I’m on this question right now, do yk the answer

Explanation:

In meiosis,  Each chromosome will divide to produce two diploid daughter cells, each of which has the same number of chromosomes.

What do you mean by meiosis?

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.

Why did you flip a coin to determine which allele would be inherited by the offspring?

Answers

You flip a coin because the allele has a 1/2 - 1/2 probability of the two outcomes as is the case when a parent is heterozygous at a locus and so there is a 1/2 - 1/2 probability for each of the two alleles getting passed on to the offspring.

The reason for flipping the coin for measuring the allele should be inherited by the offspring is because of the meiosis process.

What is the meiosis process?

It is the process at which there should be an individual cell that split twice for generating the four cells comprise the half of the original amount of genetic information.

Also, it is to be treated as the s-ex cells like sperm in males, and eggs in females.

Moreover, the DNA should be received.

Determine the temperature of the bar on the fahrenheit scale.

Answers

Answer:  

Determining bar temperature on Fahrenheit scale -

The temperature of the bar is given as 50 degrees Celsius.

If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.

We know

C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.

Now,

50/5 = (F-32) / 9

Or, (F-32) / 9 = 10

Or, F-32 = 90

Or, F = 90 + 32

Or, F = 112 degrees Fahrenheit.

That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the stroma. The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the thylakoid membrane. The Calvin cycle is the light-independent stage of photosynthesis and occurs in the stroma.

Answers

The true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"

Photosynthesis is generally the process whereby cells of autotrophic organisms obtain their food in form of sugars in the presence of sunlight. The photosynthetic process occurs in two stages namely: light dependent and light independent stage.

The light dependent stage is the first stage, which occurs in the thylakoid membrane of the chloroplast. In this stage, ATP and NADPH is produced for the second stage.

LIGHT INDEPENDENT STAGE is also known as CALVIN CYCLE. It is so called because it does not need light to occur. This stage occurs in the STROMA, where the glucose is synthesized.

Therefore, the true statement about calvin cycle is "The Calvin cycle is the light-independent stage of photosynthesis and it occurs in the stroma"

which term names part of the peripheral nerves system A spinal cord B brain C sensors​

Answers

Answer:

[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]

Explanation:

There are two divisions of the nervous system: the central and peripheral.

The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.

The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).

So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors
