Explanation:

DNA damage can affect normal cell replicative function and impact rates of apoptosis (programmed cell death, often referred to as 'cellular senescence'). Alternatively, damage to genetic material can result in impaired cellular function, cell loss, or the transformation of healthy cells to cancers.

Answer:

Why was the theory of spontaneous generation a hindrance to the development of the field of micrbiology? Spontaneous generation, proposed by Aristotle, was believed for 2000 years. ... Although his experiment showed no spontaneous generation it was said that his sealed vials did not allow air for organisms to thrive.

Explanation:

In water cycle, liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds.

The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water evaporates and becomes water vapor.

Tundra is located on the artic zone. Therefore, permanently frozen soil and low precipitation is the reason of hindered plant growth.

A biome is an ecological unit that depicts the occurrence of a biological community in response to the particular climate and the environment.

Biomes support variety of habitats across the different continents. Various biomes together constitute a biosphere.

A biome is identified on the basis of temperature and precipitation it receives annually. The presence or existence of organisms is dependent on these two factors.

Based on topography, biomes can be classified into terrestrial, fresh water and marine biomes.

Some of the well known examples of biomes include tundra region, taiga region, grasslands, desserts and forests.

There are also special types of biomes known as ecotones where the two biomes merge. Salt marshes are the example of ecotone.

Thus, biome is the life supporting unit in ecology.

Answer:

The major difference between DNA and RNA is that DNA is double-stranded and RNA is single-stranded. DNA is responsible for genetic information transmission, whereas RNA transmits genetic codes that are necessary for protein creation. DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

Answer:

RNA uses predominantly uracil instead of thymine present in DNA.

Explanation:

That’s what RNA has that DNA doesn’t.

Answer:

induction or repression of enzymes

Explanation:

Hormones are chemical messengers which are secreted by endocrine glands and regulate the rate of existing activities, usually through the induction or repression of enzymes within distant target cells via the endocrine system. They travel in the bloodstream, having slower, but longer lasting effect and are effective in small quantities.

hope it helps

The mechanism by which the secretion of a hormone is followed by travel to a distant target cell is primarily through the bloodstream. Once in the bloodstream, hormones are carried throughout the body, allowing them to reach their target cells or tissues.

Hormones are usually released in small amounts but have potent effects on target cells. The binding of a hormone to its specific receptor triggers signaling pathways within the target cell, leading to changes in cellular function or gene expression.

The travel of hormones through the bloodstream ensures their widespread distribution and enables them to reach distant target cells located in different organs or tissues.

This mechanism allows hormones to exert their regulatory effects on various physiological processes, including growth and development, metabolism, reproduction, and homeostasis.

Answer:

B

Explanation:

The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2

the answer is not exact, but it is the closest to the actual equation

The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.

Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.

The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.

Thus, option B is the correct option.

Answer:

A B and C

Explanation:

Crossing over breaks, exchanges and rejoins chromosomes at corresponding points so introduces genetic variation. Because of crossing over offspring has characters of both parents.

Also independent assortment means that during separation of the chromosomes in anaphase, any chromosome can pair up with another. So for example if we have one parent plant with yellow and wrinkled seeds and other one with green and round seeds, then the gene responsible for round seed can pair up with either of the genes responsible for yellow seeds or green seeds. Hence the characters of offspring differ from the parents, it can have yellow round seeds or yellow wrinkled seeds and so on.

Mitosis will only produce 2 daughter cells which are exactly like their parent cells and are also identical to each other. Binary fission is a form of Asexual reproduction so it does not involve shuffling of genes from 2 parents.

Because of fertilization of egg with a sperm the maternal genes and paternal genes mix together. So it also produces genetic variations.

Answer: The first low of motion states that an object at rest remains at rest and an object in motion remains in motion unless acted on by an unbalanced force. This is also knows as the law of inertia. One example of this is a ball. A ball stays put unless you push in which case it keeps on moving. However, it stops because of the force known as friction.
