Pesticides such as DDT cause liver tumors in mice and cancer in humans.

what is DDT ?

The first of the current synthetic pesticides, DDT (dichloro-diphenyl-trichloroethane), was created in the 1940s. Malaria, typhus, and other human illnesses spread by insects were the first to be successfully treated with it in both military and civilian populations. Additionally, it worked well to control insects in houses, institutions, gardens, dwellings, and crop and livestock production. Due to DDT's widespread usage and early effectiveness as a pesticide in the US and other nations, many insect pest species have developed resistance to it.

DDT is:

a substance that is known to be extremely persistent in the environment, builds up in fatty tissues, and

in the high atmosphere, may travel great distances.

Although the concentration of DDT in the environment and animals has dropped since it was no longer used in the United States, residual danger from earlier usage is still present due to its persistence.

Concerns about hazards to the environment, wildlife, and public health led to the EPA's 1972 prohibition. A possible causal link between DDT exposure and reproductive impacts is also postulated.

Explanation:

Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.

A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.

Given,

Autosomal dominant = Bb (beard), W (black coat)

Autosomal recessive = B+ (beardless ), w (white coat)

Parent = B+Bb Ww male and B+Bb Ww female

The cross between the parent is attached to the image below.

From the cross, it can be said that:

From the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.

The simple process of natural selection causes long-term population changes in living things. It can be broken down into five basic processes, which we'll collectively term to as VISTA in this case: Difference and inheritance.

One method that propels evolution is natural selection. It happens when organisms have inherited features that increase their chances of surviving. These animals procreate more frequently than individuals in the population who lack these qualities because those who have made these adaptations pass on their advantageous traits to subsequent generations.

One of the mechanisms or causes of evolution is natural selection. Physical or behavioural characteristics that help an organism fit in with its surroundings are called adaptations.

During the aerobic oxidation of carbohydrates, acetyl-CoA is produced through a series of metabolic reactions known as glycolysis and the citric acid cycle. During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation.

Pyruvate then enters the mitochondria, where it undergoes further processing to produce acetyl-CoA. This conversion occurs through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and combines with coenzyme A (CoA) to form acetyl-CoA. Acetyl-CoA is a key molecule in energy metabolism and serves as a precursor for the citric acid cycle.

During the aerobic oxidation of fatty acids, acetyl-CoA is produced through a process called beta-oxidation. Fatty acids are broken down into two-carbon units, which then combine with CoA to form acetyl-CoA. This process occurs in the mitochondria, where fatty acids are sequentially cleaved into acetyl-CoA molecules. The acetyl-CoA molecules can enter the citric acid cycle to generate energy through oxidative phosphorylation.

Once acetyl-CoA is produced, it enters the citric acid cycle, also known as the Krebs cycle or TCA cycle. In this cycle, acetyl-CoA undergoes a series of enzymatic reactions, resulting in the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the electron transport chain to generate ATP through oxidative phosphorylation.

Explanation:

Hanna would have covered 30 kilometers in half an hour if she had been travelling northeast at a speed of 60 km/hr.

She can travel 60 km in an hour because her velocity is 60 km per hour. As a result, she covers 30 km in a half hour at her pace.

The vector quantity velocity (v), denoted by the equation v = s/t, quantifies displacement (or change in position, s), over change in time (t). As shown by the equation, speed (or rate, r) is a scalar quantity that measures the distance travelled (d) over the change in time (t).
