What do scientists do when experiments are not possible
Answer:
Well, to be honest I think that they might just figure out another way to do that experiment.
Explanation: My reasoning is, that if an experiment isn't possible due to complications like maybe it could be to dangours or it could have reaction that they don't know about. So if they aren't able to do an experiment then they might find a safer one to do or they might just skip it and research more about it and see how it would react to certan things.

- Chromosomes are made of DNA that contain genes that control the production of ______ within the cell.
Chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.
What is the significance of DNA as a blueprint?The DNA acts as a blueprint in which all of the cell's information is stored, such as in the form of a gene, which is later expressed in the cell in the form of polypeptides, proteins, enzymes, and so on by the translation process, and controls and regulates the cell for various functions. DNA contains lots of genes, but not all of them are expressible.
Hence, chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

Answer:
Please find the description and it's pair below:
Homologous chromosome pairs - DIPLOID
Designated N - HAPLOID
Designated 2N - DIPLOID
Has one member of each
homologous chromosome pair - HAPLOID
Includes gametes - HAPLOID
Includes somatic cells - DIPLOID
Heart and liver cells - DIPLOID
Sperm and Egg cells - HAPLOID
Explanation:
1. Diploid organism is an organism with two sets of chromosomes, with each set contributed by each male and female parent. Chromosomes from the male parent is found side by side with chromosomes from the female parent to form HOMOLOGOUS CHROMOSOME PAIR in a diploid organism. Diploidy is denoted by 2N, where N represents number of one set of chromosomes. Diploid cells include somatic or body cells such as heart and liver cells.
2. Haploid organisms are organisms that contain one set of chromosome, formed as a result of meiotic division of diploid cells. Hence, a haploid cell contains one member of each homologous chromosome pair. Haploidy is denoted by N, meaning number of one set of chromosome. Haploid cells include gametes or sex cells such as sperm and egg cells.

capacity because the growth rate
is positive.
Answer:
Choice: (A) The herd has reached its carrying capacity because the growth rate is negative.
Explanation:
The herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.
What is ecosystem?Ecosystem is defined as a ecology's structural and functional unit where living things interact with one another and their surroundings. Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They provide tools and raw ingredients for producing medicines and other goods. Major elements of many ecosystems include plants, animals, insects, microorganisms, rocks, soil, water, and sunlight.
Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. More food supplies are available, finding a mate requires less migration for individuals, and organisms are better protected from predators.
Thus, the herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.

molecule be able to reach the mitochondria faster if the cell had a smaller
volume or a larger volume? Explain.
Answer: THE TRANSPORT OF A MOLECULE FROM THE CELL MEMBRANE TO THE MITOCHONDRIA WOULD BE FASTER IN A CELL WITH A SMALLER VOLUME BECAUSE THERE WOULD BE LESS DISTANCE TO TRAVEL
Explanation:
I hope this helped
Glucose is a simple sugar that constitutes of carbon, hydrogen and oxygen atoms. It is the most abounding monosaccharide out of all the carbohydrates.
The glucose molecule will move actively to the mitochondria from the cell membrane if the membrane has a smaller volume.
The reason for the answer is:
Smaller the cell size less will be the covering space, hence the molecule will move less distance to reach its target.Mitochondria uses glucose molecules and generates carbon dioxide as the waste material.It is not always beneficial for the cell to be larger sometimes smaller cells can be more dynamic.Therefore, the glucose molecule will travel faster when the cell membrane has a small volume.

compare and contrast coal and nuclear power. would you support either of both of these forms of energy technology. why or why not?
Answer:
I will give you a basic idea of what you should write in my opinion you should support neither of these forms of energy mainly due to the reason that both forms of energy pollute the world. instead we should focus on using renewable energy such as solar wind and hydro. furthermore coal and nuclear power are non-renewable resources which means that there is only a limited amount on the earth which brings up the benefit of having renewable energy as there is endless supply of it.
This DNA strand consists of eight pairs of nitrogenous bases. How many different sequences of eight bases can you make? Explain how you found your answer.
Answer:
In the sequence of 8, it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.
There are 65,536 different possible sequences in a DNA strand consisting of eight pairs of nitrogenous bases.
We have a DNA strand consisting of eight pairs of nitrogenous bases and we want to know how many different sequences of eight bases can we make, that is, how many combinations are possible.In DNA, there are 4 kinds of nitrogenous bases: Adenine (A), Guanine (G), Thymine (T) and Cytosine (C).Each position (P) can be occupied by any of the 4 bases (B). Since there are 8 positions, and the bases can be repeated, we can calculate the total number of different sequences (N) using the following expression.

Answer:
Photosynthesis is when plants convert sunlight, water, and oxygen into energy.
photosynthesis is how plants grow
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.

why virus is imortal?
Answer:
Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Explanation:
Answer:
A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.

Explanation:
SodiumSilicon MagnesiumName and describe 3 ways objects can travel across a membrane. Include what types of objects (H2O, sugar, ect) are moving across the membrane for each way.
Answer:
Osmosis - water
Ions - diffusion
Large proteins - endocytosis
Explanation:
Ions and small molecules can cross the cell membrane by simple diffusion, where they move from a high concentration to a low concentration, down a concentration gradient.
Osmosis is the process whereby water travels across a semi-permeable membrane from a high concentration to a low concentration.
Larger cargo can cross the membrane through a process called endocytosis, where the membrane engulfs the particles and brings them inside the cell, encased in a vesicle.
