What are these answers?

1. Nucleotides: A phosphate group, a 5-carbon sugar, and a nitrogenous base are the three components of a nucleotide. Adenine, cytosine, guanine, and thymine are the four nitrogenous bases in DNA. Instead of thymine, uracil is found in RNA. The genetic material of all known living creatures is made up of nucleotides in a chain.

2. Genes:  A gene is a small segment of a lengthy DNA double helix molecule that consists of a linear base pair sequence. A gene is any portion of DNA that contains instructions that allow a cell to generate a specific product – usually a protein, such as an enzyme – that performs a single specified action.

3. A locus (plural loci) is a stable location on a chromosome where a certain gene or genetic marker can be found.

4.  At a genomic region, an allele is one of two or more variations of DNA sequence (a single base or a segment of nucleotides).

5.  Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

6.  Karyotype: A karyotype is a individual's entire set of chromosomes. A laboratory-produced representation of a person's chromosomes extracted from an individual cell and arranged in numerical order is also known as a chromosomal map. A karyotype can be used to check for chromosomal number or structural problems.

8. Genotype: An organism's genotype is its genetic makeup. From embryonic development to adulthood, the genotype determines an individual's inherited potentials and limitations. In se×ually reproducing organisms, a person's genotype is made up of the whole set of genes acquired from both parents.

9. Phenotype: Physical traits are described by phenotypes. It encompasses both apparent (such as hair or eye color) and measured characteristics (like height or weight). Characteristics relevant to your development and behavior, such as personality traits, are also referred to as phenotypes.

Explanation:

Different circumstances cause different outcomes, animals adapt to certain conditions and their surroundings.

Letter C isn't incorrect but that is not what the question is asking C.Organisms can learn new adaptations.

but other than those two the rest are incorrect.

The genotypes and phenotypes their offsprings can have include only free lobes and attached hair.

This is defined as the genetic constituent of an organism while phenotype represents the physical characteristics.

Dd and Ee when crossed will give DE, De, dE and de which means that the genotype will be 1 homozygous dominant,2 heterozygous and 1 homozygous recessive for free lobes and attached hair.

The probability = number of favorable outcome/ total number of outcome.

The total number of outcome = 4

The probability for 1 homozygous dominant,2 heterozygous and 1 homozygous recessive is therefore 1/4 , 1/2 and 1/4 respectively.

In a metapopulation, source populations are species that are likely to have more individuals immigrating to habitat patches than other species. This means that source populations can inhabit the largest suitable ecological patch.

A population may be defined as the members of the same species living in a particular area at a given time.

A metapopulation is a collection of the regional populations within some more extensive area, where migration from one population to another is possible.

Therefore, it leads to inhabiting the largest suitable ecological patch.

Which of these equation is the correct one for fermentation?

❍ Glucose + oxygen → carbon dioxide + water

❍ Glucose → lactic acid

❍ Glucose → ethanol + carbon dioxide

To understand this first we should know what is fermentation.

What is fermentation?

A process of chemical change in food or drink because of the action of yeast which may cause it to produce bubbles or heat, or turn sugars in it into alcohol.

Equation -:

[tex] \small\sf{C_{6}H_{12}O_{6} \rightarrow2C_{2}H_{5}OH + 2CO_{2}} [/tex]

Which means

Glucose → ethanol + carbon dioxide

Answer:

While exercising, the muscles need additional energy as the breathing rate and volume of each breath increase to bring more oxygen into the body and remove the carbon dioxide produced. If insufficient oxygen is available to the muscles, for instance, the exercise is vigorous and/or prolonged, the heart and lungs are unable to supply sufficient oxygen. Muscles begin to respire anaerobically. Lactic acid is produced from glucose, instead of carbon dioxide and water. Muscles continue to contract, but less efficiently. When a period of exercise is over, lactic acid must be removed, because the body's tolerance to lactic acid is limited. These processes require oxygen. This is why, when the period of activity is over, a person’s breathing rate and heart rate do not return to normal straight away.
