Mitosis occurs in living things when a cell divides to produce two cells. Compared to the original cell, how many chromosomes are in each of the resulting cells?
A.The same number
B.Twice as many
C.Half as many
D.An unpredictable number
A
Explanation:
After mitosis, two identical cells are produced with the same original number of chromosomes of the parent's cell. In this case, if a cell has 24 chromosomes, each daughter cell will have 24 chromosomes after mitosis

In multicellular organisms, cell growth and division is very controlled. Some cells like muscle and _______ cells stop dividing after maturity. Other cells like ______ and blood cells grow and divide rapidly through life. _______ are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to ______.
The growth and development of an organism are dependent on the control and coordinated activities of the cells, tissues, and organs.
The correct blanks for the given paragraph are:
In multicellular organisms, cell growth and division are very controlled. Some cells like muscle and nerve cells stop dividing after maturity. Other cells like Skin and blood cells grow and divide rapidly through life. Cyclins are proteins that regulate the timing of the cell cycle, "telling" the cell when to divide. If cells stop responding to regulation, uncontrolled cell growth can lead to cancer.
The statements can be explained as:
The muscle and nerve cells stop dividing after maturity. The nerve cells lack centrioles, which play a crucial role in the division of cells. Thus, the nerve and muscle cells do not divide. The skin and blood cells divide continuously and throughout life. The cells when are damaged or dead, these cells replace them. Cyclins are the proteins, which regulate and activate the cell cycle by binding with the cyclin-dependent kinases.Cancer is repetitive and uncontrolled cell growth. It can be caused due to failure of regulation of cell cycle or any carcinogen exposure.
Therefore, the correct answers are nerve, skin, cyclin, and cancer.

Describe some of the properties of water and explain how the structure of water is responsible for these properties.
Answer:
The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen. ... The stream of water bends due to the polarity of water molecules.

You just wrote in the template strand of DNA. Use the template strand to transcribe a strand of mRNA.
Write down the tRNA anti-codons that pair with the mRNA strand.
Answer: the codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA. Template stand is the DNA strand off which the mRNA is synthesized.
Explanation:
The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.
What is Codons?
The anticodon is the complementary three nucleotide sequence in the appropriate tRNA. Template stand is the DNA strand off which the mRNA is synthesized.
Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein synthesis (stop signals). There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.
The bases that make up DNA and the associated messenger RNA are called bases. These nucleotides are frequently identified in RNA by the letters A, U, C, and G.
Therefore, The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.

These are unicellular organisms that have been around 3 and a half million years and consider as the first photosynthetic organisms responsible for the availability of oxygen on earth. These cells are also considered as the cell that evolved in the eukaryotic cells by differentiation around 2 billion years ago. The aggregated form of the cells are known as the mats.

Hope this helps!
According to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.
What is Community?A Community may be defined as a group of individuals belonging to different species living in the same area at a given time.
The individual is the unit of the population, while the population is the unit of evolution. This form of evolution is significantly required in order to construct a community where the different groups of individuals of different species are gathered in such a way that one depends on another.
Therefore, according to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.

Answer:
b
Explanation:
Photosynthesis is the process of preparing food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.
The correct option is:
Option B. chemical energy in the bonds of organic molecules like glucose
The process of photosynthesis involves:
Photosynthesis is carried out by plants. The leaves are the primary site for photosynthesis. The chloroplasts present in the plant cells are primarily involved in photosynthesis. Photosynthesis involves the capturing of light energy and storing it in the form of bonds of organic molecules like glucose and starch. The process involves carbon dioxide, water, sunlight, and green pigment chlorophyll to carry out photosynthesis. The products of the process are oxygen and sugar molecules holding the energy.

Two characteristics of most plants are a root system and a shoot system. Most of the structures in these systems are common to all plants; however, there are some variations. Which structure can sometimes be found as part of the shoot system? Stems leaves roots flowers
Answer:
stems, leaves, flowers
Explanation:
There are two parts in the plants ----
1. the shoot system
2. the root system
Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.
The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.

Which mechanism explains how both A and B antigens produce type AB blood?
Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

RNA interference (RNAI) is a mechanism of gene regulation in eukaryotes. RNAI is initiated by ____, which leads to the ____ of specific genes.
Box 1:
single-stranded RNA
double-stranded RNA
double-stranded DNA
Box 2:
silencing
induction
expression
Answer:
double-stranded RNA; silencing
Explanation:
The RNAi mechanism is a natural process of gene silencing triggered by different small non-coding RNAs such as, for example, siRNAs, miRNAs and piRNAs. RNAi is a powerful technique to induce gene silencing in a sequence-specific manner. The delivery of exogenous double-stranded RNAs (dsRNAs) can be used to induce this evolutionarily conserved mechanism. The dsRNAs first bind to RNAi core components (Ago, Piwi proteins) and then target complementary mRNAs to induce their degradation.
