Answer: Warm air rises and causes high air pressure. Cold air stays closer to earth and causes low air pressure which is known as low pressure. When there is a low-pressure system in the area-  In contrast, a high-pressure system allows for rain clouds "I believe since water vapor is formed when water is heated and it can form when something heats".

Basic unit of life is cells

Answer:

The Cell Theory Is a Biology Unifying Principle

Explanation:

According to the cell theory, all biological entities are made up of cells; cells are the basic unit of life, and all life originates from pre-existing life. The cell theory is now so well-established that it serves as one of biology's unifying principles.

Explanation:

Answer:

The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population. If it were smaller, the primary consumers would have eaten them all up and eventually would die out because they would have no more food source. This would be bad for all higher-level consumers.

If, while examining a human karyotype, it is observed that there are 22 paired chromosomes and two chromosomes that are not the same size, this would most likely be due to mutation.

Mutation is any change in the nucleotide or chromosomal sequence of a genome.

There are different types of mutation and they include;

Photosynthesis ceases when leaves wilt, mainly because stomata close, preventing CO2 from entering the leaf.

Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates in presence of light.

Photosynthesis requires carbon dioxide and light to produce glucose and release oxygen.

In plants, the interchange of carbon dioxide and oxygen during photosynthesis occurs in specialized structures called stomata.

Answer:

two sister chromatids

Explanation:

There are two sister chromatids that each chromosome have in the Anaphase of meiosis I.

Chromatids may be defined as one of the two similar halves of a chromosome that has been duplicated in preparation for cell division.

During Meiosis I, each of the daughter cells is haploid (n) in nature and consists of 23 chromosomes. Each chromosome comprises of 2 sister chromatids.

Therefore, there are two sister chromatids that each chromosome have in the Anaphase of meiosis I.

Answer:

Mountain Pine Beetle.

They only attack in Douglas Fir Trees.

Deforestation increases the risk of floods in an area tree roots improve soil water retention.

When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.

When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.

Thus, option "D" is correct.

Answer:

The structural and functional units of the kidney are called nephron.

Fun Facts about Nephron:

Nephron is the structural and functional unit of the kidney.

Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.

The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.

The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.

A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.

Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.

Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.

Therefore, the structural and functional units of the kidney are called nephrons.
