This paragraph attempts to explain the rain shadow effect, but it gets some of the facts wrong. Identify the inaccurate statemen
EleoNora [17]

The inaccurate statements are:

- Warm, moist air goes up the mountain on its leeward side, where its water content condenses to precipitate as rain or snow;

- This side is called the windward side and, compared with the leeward side, receives hardly any rainfall;

In the description, the windward and the leeward sides of the mountain are mistaken, or rather have switched positions.

The windward side is the side where the warm, moist air where the water condensates and results in rainfall or snow. Thus this is the side of the mountain that is wetter and is covered with denser vegetation.

The leeward side is the side that doesn't receive warm and moist air, and the amount of precipitation is usually very low. This makes the leeward side very dry in most cases, and very often it is the reason for the formation of arid and semi-arid areas.

Match the biological structure with its metaphorical equivalent Question 5 options: Movie Authors Words Chapter variations Scrip

1. Nucleotides: A phosphate group, a 5-carbon sugar, and a nitrogenous base are the three components of a nucleotide. Adenine, cytosine, guanine, and thymine are the four nitrogenous bases in DNA. Instead of thymine, uracil is found in RNA. The genetic material of all known living creatures is made up of nucleotides in a chain.

2. Genes:  A gene is a small segment of a lengthy DNA double helix molecule that consists of a linear base pair sequence. A gene is any portion of DNA that contains instructions that allow a cell to generate a specific product – usually a protein, such as an enzyme – that performs a single specified action.

3. A locus (plural loci) is a stable location on a chromosome where a certain gene or genetic marker can be found.

4.  At a genomic region, an allele is one of two or more variations of DNA sequence (a single base or a segment of nucleotides).

5.  Chromosomes are thread-like structures found within the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA). DNA is passed along from parents to children and carries the precise instructions that distinguish each living thing.

6.  Karyotype: A karyotype is a individual's entire set of chromosomes. A laboratory-produced representation of a person's chromosomes extracted from an individual cell and arranged in numerical order is also known as a chromosomal map. A karyotype can be used to check for chromosomal number or structural problems.

8. Genotype: An organism's genotype is its genetic makeup. From embryonic development to adulthood, the genotype determines an individual's inherited potentials and limitations. In se×ually reproducing organisms, a person's genotype is made up of the whole set of genes acquired from both parents.

9. Phenotype: Physical traits are described by phenotypes. It encompasses both apparent (such as hair or eye color) and measured characteristics (like height or weight). Characteristics relevant to your development and behavior, such as personality traits, are also referred to as phenotypes.

Which is a correct statement of Newton's second law?
SSSSS [86.1K]

Answer:

When an object experiences a net force, it will accelerate at a rate determined by its mass

Explanation:

A body at rest is considered to have a zero speed, so any force causing the body to move is an unbalanced force and any force causing the body to slow down is also an unbalanced force. An unbalanced force cause acceleration or deceleration i.e a change in speed

PLEASE HELP I only have tomorrow morning to get my grade up.
Anika [276]

oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.

i hope you will get some knowledge from here❣
