Describe the process of respiration which takes place in human beings whe
oxygen is not available and give an effect.
(T
Answer:
The process in which respiration takes place without oxygen is called as anaerobic respiration.
Aerobic respiration In anaerobic respiration the energy produced is very low as compared to aerobic respiration The organisms which use this type of respiration process are fungi, yeast In this process, (in yeast) glucose broke down into pyruvate and gives ethanol , carbon dioxide and energy In human muscle cells when there is a lack of oxygen this process occurs in which lactic acid and energy are produced.More to know -Pyruvate is three carbon -molecule.
The build up of lactic acid causes cramps in muscles.

Answer:
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Can someone help me out with this? In pea plants, the allele for green seeds (G) is dominant over the allele for yellow seeds (g). • Parent 1: homo-zygous for green seeds • Parent 2: homo-zygous for yellow seeds. • What are the gametes each parent plant will produce? Parent 1: Parent 2:
Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes

During the process of photosynthesis, energy from the Sun is converted into A) chemical energy in the bonds of inorganic molecules B) chemical energy in the bonds of organic molecules like glucose C) enzymes used to produce inorganic molecules D) enzymes used to produce organic molecules
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.
Thus, the correct answer is option B.

Why are there two sets of phases during meiosis, but only one during mitosis? Think about what is different about meiosis and mitosis
Answer:
Mitosis is the cell cycle for somatic cells which are diploid (2n).
Meiosis is the cell cycle for germ cells (gametes) where they are haploid (n) so that is why they have two sets of phases.
Explanation:
Before cells divide, they must replicate their entire genome. Explain why
replication of the genome prior to cell division is important.
Each time a cell divides into two daughter cells, its full genome is duplicated; for humans and other complex organisms, this duplication occurs in the nucleus. This minimizes the incidence of errors (mutations) that may greatly affect the resulting organism or its offspring. ...
HOPE THIS HELPED <3
Answer:
In order for all of the cells in your body to maintain a full genome, each cell must replicate its DNA before it divides so that a full genome can be allotted to each of its offspring cells. If DNA replication did not take place fully, or at all, the offspring cells would be missing some or all of the genome.

Centrioles play a notable role in cell division. ... These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division. Though centrioles play a role in the mitosis of animal cells, plant cells are able to reproduce without them.

what is the building block of nucleic acids
Answer:
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
I found this on google because I am not the best at explaining things but I hope this helps :)
The building blocks of nucleic acids are nucleotides, which consist of a sugar molecule, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
What are nucleotidesNucleotides are the building blocks of nucleic acids, such as DNA and RNA. They consist of a sugar, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
Nucleotides link together through phosphodiester bonds, forming the backbone of nucleic acid chains. The sequence of nitrogenous bases along the chain encodes genetic information. Adenine pairs with thymine or uracil in RNA, while guanine pairs with cytosine, creating complementary base pairs.
Nucleotides play a crucial role in storing and transmitting genetic instructions, serving as the foundation for DNA and RNA molecules.

x + (2x + 40) + (3x – 50) = 15,002
Reorder the terms:
(x+2x+3x)+(40-50)=15,002
Combine like terms:
x+2x+3x=6x
40-50=-10
