Question 7 of 10 What is the product of meiosis |I? O
A. Four haploid cells
B. Two diploid cells
C. Two haploid cells
D. Four diploid cells
Answer:
A. Four haploid cells
Explanation:
In this division, the secondary spermatocytes and oocytes, which contain 23 chromosomes each and are diploid in the amount of DNA, are divided into two cells, each of which will have 23 chromosomes, but twice the amount of DNA, since in anaphase there was a separation chromosome to sister chromosomes, reducing the amount of DNA by half.
As a result of this division in males in the process of spermatogenesis from the initial, diploid spermatogonia or primary spermatocytes, 4 cells are formed - spermatids that have a haploid number of chromosomes and twice less DNA than the cells from which they were formed.
Answer:
2 haploid cells

Explanation:
Scientist observed an organism X and noted down the mode of nutrition as follows X secretes enzymes outside its body and digests food with these enzymes. It then absorbs the digested food. Which organism was observed by the scientist?
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.

How does the moon cause tides?
The pull of the moon on Earth causes the water level on the shores to fluctuate.
The moon's gravitational pull acts on Earth.
The moon dries up Earth during different times of the month.
As the moon's gravity pulls on Earth, the ocean water is pulled toward it.
The moon pushes down on Earth and causes the water to rise.
Answer: 1, 4, 5
Explanation:
The moon always pulls on the tides, and in certain moments like the equinoxes the moon will set a patterned tide for the rest of the month, since the moon is being flung around in earths orbit, its gravity causes it to pull on the most flucuate object on earth: water. And if you have glass of water then put your hand into it you will see how your hand displaces the water.!

Which type of cell division is associated with genetically identical, diploid cells?
O. Meiosis
O Fragmentation
Mitosis
O
Somatic division
Answer:
Mitosis
Explanation:
This occurs in the stages of mitosis.
The diploid cells have two copies of each chromosome. These go on to produce sperm and egg cells.
Mitosis is where the cells separate and create identical copies.
What is a mistake or change in DNA called?
Answer:

7. Which of the following statements is not
true of enzyme behavior? (pp.78–79)
a. Enzyme shape may change during
catalysis.
b. The active site of an enzyme orients its
substrate molecules, thereby facilitating
interaction of their reactive parts.
c. All enzymes have an active site where
substrates are temporarily bound.
d. An individual enzyme can catalyze a
wide variety of different reactions.
Answer:
c
Explanation:
The statement which is not true about enzyme behavior is that all enzymes have an active site where substrates are temporarily bound.
Enzymes are proteins that can act as biological catalysts by increasing the rate of chemical reactions. The molecules upon which enzymes may act are known as substrates, and the enzyme which converts the substrates into different molecules are known as products. Almost all metabolic processes which take place in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
Metabolic pathways depend upon the enzymes to catalyze individual steps. The study of enzymes is called as enzymology and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and thus have unusual 'pseudocatalytic' properties.
Thus, statement which is not true about enzyme behavior is C.

Why do fish and frogs lay eggs in hundreds whereas a hen lays only one egg at a time?
Answer:
bc there eggs are tinnier then a hens egg
Explanation:
Answer:
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.
Could anybody help me on this please
Answer:
The term genotype refers to the genetic characteristics of an individual. Many genes have different variations, which are called alleles. As we inherit genes from both of our parents, we inherit one allele from each of them. The combination of alleles we possess is in fact our genotype.
The term phenotype refers to our physical characteristics. They are heavily influenced by our genotype, but they can also be affected by environmental factors (unlike the genotype).
As an example of genotype, we can mention eye color. Brown eyes are a result of dominant alleles (B), while blue eyes are a result of recessive alleles. If a person has one (Bb) or two dominant alleles (BB), their eyes will be brown, and if they have both recessive alleles (bb), their eyes will be blue.
As an example of phenotype, we can mention skin color. The amount of melanin we produce will depend on our genotype. A person whose skin cells produce more melanin will have darker skin. However, our melanin can start getting darker after longer exposure to UV light, which results in skin darker than what is dictated by our genotype.
