Explanation:

Answer: The answer is A

Explanation:

Society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

DDT is defined as the 1940s saw the development of the first synthetic modern pesticide. It aided in the prevention of illnesses like typhus and malaria. Researchers classify DDT as an endocrine-disrupting chemical, or an EDC, because there is evidence that it alters and disrupts hormones crucial for healthy health, including reproductive health, as well as neurological and immunological processes.

Even while scientists began to raise concerns about such risks in the middle of the 1940s, it wasn't until the publication of Rachel Carson's book Silent Spring in 1962 that the use of the chemical became the subject of broad public concern. DDT, often known as dichlorodiphenyltrichloroethane, is a pesticide used in farming. DDT usage was outlawed in the US in 1972. DDT is still used in several non-American nations to keep mosquitoes that cause malaria at bay.

Thus, society was positively impacted by increased insect control in crops, but it was negatively impacted by harmful chemicals. Hence option A is correct.

Explanation:

Every animal-like cell has two small organelles called centrioles. They are there to help the cell when it comes time to divide. They are put to work in both the process of mitosis and the process of meiosis.

Answer:

The no. of heterozygous carriers = 0.0392

Explanation:

From the given information:

The incidence of this recessive disorder i.e. q² = 1/2500

q² = 0.0004

q = 0.02

From Hardy Weinberg's Equilibrium.

p + q = 1; &

p² + 2pq + q² = 1

∴

p + 0.02 = 1

p = 1 - 0.02

p = 0.98

So, the numbers of heterozygous carrier 2pq is:

= 2 × 0.98 × 0.02

= 0.0392

Explanation:

Answer:

Object with 200kg

Explanation:

Newton's second law of motion depicts how the acceleration of an object depends on the force (F) and mass of the object (m). This law can be represented by the mathematical equation: F = ma

However, the acceleration of the object is inversely proportional to the mass i.e. a = F/m. This means that an increase in the mass of an object causes a decrease in acceleration of the object and vice versa.

According to this question, If the forces acting on two objects are the same, an object that is 200 kg will have a greater acceleration than an object that is 400 kg. Note: the higher mass the mass, the lower the acceleration and the lower the mass, the higher the acceleration.

Answer:

eight million

Explanation:

Eight million different ways can the 23 homologous pairs in a human germ cell.

One of a pair of chromosomes with the same gene sequence, locations, chromosomal length, and centromere placement is referred to as a homologous chromosome. One paternal and one maternal chromosome make up a homologous pair.

A somatic cell of a human has a total of 46 chromosomes in its nucleus. The father inherits half of them (22 autosomes Plus X or Y chromosome), while the mother inherits the other half (22 autosomes + X chromosome).

A female typically has 23 homologous chromosomes, compared to a male's 22. This is due to the fact that men' X and Y sex chromosomes are not identical. During meiosis, homologous chromosomal pairing is crucial.

Therefore, Eight million different ways can the 23 homologous pairs in a human germ cell.

Answer: Mendel's research lead to several conclusions about the traits and its passing through generations. The two of the conclusion are different forms of a gene account for variation in the inherited traits and some alleles are dominant over others for a given trait.

Explanation

George Mendel was a famous biologist. His research was on genes and traits. His experiment shows how genes gets transferred from parents to offspring. Also he stated about the behavior and dominance and recessive nature of that alleles.

He also gives the possibility of dominance of a trait over other trait. The different forms of gene are responsible for various types of inherited traits in an organism.

Electric eels are part of a group of animals called electric fish.These cells pump positively charged sodium atoms, called ions, from inside themselves to the outside.

Explanation:

Brainliest? plz

Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.

An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.

The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.

If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.

scientists can determine the evolutionary relationships between different organisms by comparing their appearances, figure, and body internal and external structures.

Explanation:

Scientists utilize DNA to evaluate evolutionary relationships, along with resemblance in early development and bone structure.

Organisms with similar physical characteristics and genetic sequences are more strongly linked than those that do not.

Homologous structures are components that overlap both anatomically and genetically; the similarities stem from shared evolutionary paths.

through protein channel

Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.

Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.

Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

Cellular Respiration codes for development and growth. The correct option is C.

Thus, DNA (deoxyribonucleic acid), which makes up the majority of genetic material, contains the instructions for an organism's growth and development. The instructions or genetic code that determines an organism's traits, capabilities, and attributes are found in its DNA.

The genetic code is used to produce proteins and other compounds required for growth and development through the process of gene expression. Through reproduction, this genetic information is transferred from parent to child, maintaining a trait's continuity over generations.

Cellular respiration (c) is the mechanism by which cells produce energy by dissolving organic molecules, whereas heterotrophs (a) are organisms that receive their energy by eating other organisms.
