Answer:
The answer is option 3.
Explanation:
White blood cells are not responsible for removing carbon dioxide.
White blood cells contain lymphocytes and phagocytes.
Lymphocytes produce antibodies to attack pathogens while phagocytes engulf pathogens.
Removal of carbon dioxide is not a response of human white blood cells to pathogens. Thus, the correct option is 3.
What are the white blood cells?White blood cells are also called as leucocytes. These are the specialized cells of the immune system which are involved in the protection of the body against both the infectious disease and foreign invaders.
All white blood cells in the body are produced and derived from that of multipotent cells in the bone marrow which are known as hematopoietic stem cells. Leukocytes are the cells which are found throughout the body, including that of the blood and lymphatic system.
Therefore, the correct option is 3.

Explanation:
The gamete of a red fox has 19 chromosomes in it. How many chromosomes are in the red foxes DIPLOID skin cells?
Answer:
38 chromosomes are in the red foxes DIPLOID skin cells
Explanation:
There are two principal types of cells in the organism:
Diploid cells (2n) Somatic diploid cells (2n) reproduce by the process of mitosis and produce two diploid cells.Germ diploid reproductive cells (2n) also reproduce by mitosis and produce two diploid cells. But can also reproduce by the process of meiosis, suffering a reduction in the number of chromosomes and producing four haploid cells (n). Haploid cells (n)Gametes are the product of germ cell division by meiosis, and they have only one set of chromosomes, n (19 in this example). Their destiny is to merge in the process of fecundation, during which a new diploid cell called the zygote emerges through fertilization. The zygote is a complete diploid cell that suffers successive mitosis and forms a new organism (a new fox in this case).
- So, through meiosis, the diploid germ cell (2n) produces four haploid cells (n) that are the gametes.
- Through fecundation or fertilization, two gametes (n) merge and produce a diploid cell (2n) that is the zygote.
If the red fox gamete has 19 chromosomes (haploid number n, the single set of chromosomes), it must merge with another gamete (coming from the other parent) with 19 chromosomes to form the zygote. The zygote is a diploid cell. The zygote will suffer many mitosis divisions to become a new fox.
To know the number of chromosomes in a skin cell, we need to duplicate the number of chromosomes in the gamete (19).
N = 19 = Haploid number2N = 2 x 19 = 38 = Diploid numberBrown hair is dominant over blonde hair. Could two brown hair people have a blonde haired kid? Explain

Explanation:
How does the product of cell division with meiosis differ from the product of cell division with
mitosis?
The difference is that mitosis produces two diploid (2n) somatic cells that are genetically identical, but meiosis produces four haploid (n) gametes that are genetically unique from each other.

Answer:
Yes,it's clear that bees play a vital role in food production. They are excellent pollinators! Most food crops—including fruits, vegetables, nuts, and seeds—must go through pollination. That's the process of moving tiny pollen cells between plants to help them make seeds.

Is it varration , overpopulation or adaption On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own.
Answer: this is adaptation, but not in the way suggested in the question.
Explanation:
The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.
There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.
These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.
why do some scientists think the "origins" question cannot be answered scientifically?
I personally think because of the intelligent design vs. evolution theories. what do you think?
Answer:
agreed
Explanation:
for certain things like how humans were created and everything like that I totally agree because you can't really do research if something that over the years is probably either hidden or gone so if there wasn't any evidence of how any of this came to be by now it would be gone. some things you just can't put a logical explanation on

What is carbon emissions responsible for?
Answer:
Carbon dioxide (CO2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH4) and nitrous oxide (N2O) are also emitted. These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to produce electricity.
Explanation:
What can Carbon do?
Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest levels of emissions in the atmosphere. This, of course, causes global warming and ultimately, climate change. Carbon dioxide is released into the atmosphere when fossil fuels — coal, natural gas, and oil — are burned.

how do variations lead to adaptations?
Answer:
Favorable variations may allow an organism to be better adapted to its environment and survive to reproduce. Beneficial traits are favored in a population so that they may become better represented. Changes in the genetic makeup of a species may result in a new species; this is biological evolution.

Please help, 100 points! Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?
A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years. (This one is obviously wrong)
Around 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.
What is the origin of life?Even before the 3.5 billion years ago when the oldest fossils on Earth were discovered, just at the conclusion of the time of late intense bombardment, there is evidence of biological activity.
The 3.5 billion-year-old "stromatolites," which are hard structures created by bacteria, also provide evidence of their presence. Stromatolites are produced when microbe-made sticky mats catch and organize sediments into layers.
It has been discovered that trophozoites contain organic material from 3.5 billion years ago. 3.5 billion-year-old rocks have been found to contain microbial remnants, some of the planet's earliest evidence of life.
Therefore, 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

If the code on the template DNA strand is TACGCA the RNA built from that template during transcription would have the sequence type your answer..
Answer:
AUGCGU
Explanation:
According to the base-pairing rule, Thymine (T) always pairs with Adenine (A), and Cytosine (C) always pairs with Guanine (G). In addition, RNA has Uracil (U) in the place of Thymine. Following these two rules, TACGCA is transcribed as follows:
T A C G C A
A U G C G U
Hence, the transcription product of TACGCA is AUGCGU.
