A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.
What is nucleotide?It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.
These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder. The type of sugar that is used in a DNA helix is called deoxyribose.
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.
Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

Why does it rain more heavily on the windward side of mountain ranges?
A.Air masses absorb moisture as they increase in altitude, form clouds which precipitate rain.
B.Cool air on the lee side of the mountain encounters warm moist air from the windward side causing it to give up moisture.
C.Prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing rain.
D.Cool, moist air from the oceans warms over land and precipitates rain on the windward side of mountain ranges.
It rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.
What are the prevailing winds?This is a type of wind that blows in a specific direction over a certain area, and its strength can be influenced by many factors, like the elevation of the land, temperature and pressure differences between air masses, earth rotation, etc. In a mountain range, the prevailing winds carry moist air to the top of the slope, where it cools and releases precipitation, that causes the rain.
Hence, it rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.

Explain how ATP stores and releases energy
Answer:
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
Identify the tonicity of the solution surrounding the cell.
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).
Carbon dioxide may be cycled back and forth between plants and animals.

what organelles are used in passive and active transport
Molecules can diffuse across membranes via transport proteins, or they can be aided in active transport by other proteins. Organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria and peroxisomes all play a role in membrane transport.

"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.
