Answer:

Haploid, and the chromosomes are each composed of a single daughter chromosome

Explanation:

Meiosis is a type of cell division that reduces the chromosomal number of the daughter cells by half. Meiosis produces four daughter cells, which have half of the chromosomes of the parent cell. Meiotic process occurs in two division steps i.e. meiosis I and meiosis II, which each involves four stages namely: prophase, metaphase, anaphase and telophase.

- During meiosis I, homologous chromosomes (similar but non-identical chromosomes from parent), are separated into opposite poles while

- During meiosis II, sister chromatids (replicated chromosomes) separate into opposite poles.

Based on the above explanation, after TELOPHASE II of meiosis II, each daughter cell will be HAPLOID (n), and the chromosomes are each composed of a single daughter chromosome.

Answer: Point sources of pollution

Explanation:

The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.” Factories and sewage treatment plants are two common types of point sources.

Answer:

The volume of fish tank is 12 liters.

The volume of the fish tank is  12 Litres.

Volume of the fish tank is lengh×width×height  

                                          ⇒50cm×12cm×20cm

                                           ⇒  12000 cm³

1 cm³=1 ml

12000 cm³= 12000ml

1000 ml= 1 Litre

1 ml = 1/1000 Litres

∴ 12000 ml = (1/1000)×12000

          ⇒ 12 Litres

Answer:

C

Explanation:

Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen.

Animals produce carbon dioxide as a byproduct of cellular respiration. Plants use the carbon dioxide through photosynthesis to produce oxygen, thus, animals produce carbon dioxide used by plants for photosynthesis.

Photosynthesis is the method by which plants use sunlight, water, and carbon dioxide to make oxygen and energy in the form of sugar.

Thus, option "C" is correct, animals produce carbon dioxide used by plants for photosynthesis.

Answer:

Mitochondria; cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.

The structures that are part of the cortisol pathway are the hypothalamus and liver.

Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.

The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.

The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.

The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.

Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.

The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces.  When the cow contributes to the gene pool of the new herd, which of these most likely increases?

Answer:

genetic variation

Explanation:

Whenever migration occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.

Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.

For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.

The bigger the difference in allelic frequencies between populations is, the bigger is the effect of the genetic flow.

Use a punnett square! I'll attach an example.

Genotype - Genetic constitution of dominant and recessive traits inherited from parents. BB, Bb, & bb can be used to represent these.

Phenotype - Observable. If a dominant trait is present, it shows as the phenotype. For example, brown hair is dominant to blonde hair. A person with a BB or Bb genotype will have brown hair, but a person with a bb genotype will have blonde hair.

Statistically, they have a 50% chance of a child with a widow's peak, and a 50% chance of a child with a straight hairline.

The genotypic and phenotypic ratios of their offspring are 50% and 50% ratio of the child.

The heterozygous are the condition where you have inherited different forms of a particular gene from each  of your biological parents. By different shapes we generally mean that there are different parts of the gene where the sequence is different.
