Answer:a

a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

Explanation:

Answer:

Pythons and boa constrictors have tiny hind leg bones buried in muscles ... Vestigial legs are a clue that snakes descended from lizards. Over 100 million years ago, some lizards happened to be born with smaller legs, which, ... The ancestor of boas and pythons retained very small vestigial legs

Explanation:

Animals are consumers and hence they depend on other organisms (plants and other animals) for their food.

Answer:

200

Explanation:

20 times 10 is 200 easy

Answer:

200

Explanation:

Multiply 10 by 20 and you'll get 200.

10 pounds = 1 pound gained

? = 20 pound gained

10 : 1

? : 20

1 x 10 = 10

20 x 10 = 200

Hence, the killer whale will have to eat 200 pounds of seal to gain 20 pounds.

hope this helps and is right; p.s. i really need brainliest :)

Answer:

respiratory system

Explanation:

The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

1Answer:

The correct answer is - D. how changes in biodiversity impact an ecosystem.

Explanation:

The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.

These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.

The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.

Answer:

The correct answer is D

Explanation:

Answer:

Gas are well separated with no regular arrangement.

liquid are close together with no regular arrangement.

solid are tightly packed- the particles are close together.

Hope this helps:)

Answer:

Solid: Molecules are tightly together to hold the shape.

Liquid: Molecules float around to fill the space of the container that they are in.

Gas: Molecules have no definite shape and move freely.

Answer:

Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.

Explanation:

1. The conversion of liquids into gas is termed

as Evaporation.

2. The conversion of Gas into liquids is called

Condensation.

3. The falling of water droplets in the form of

rain after condensation of clouds is called

Precipitation.

4. The cyclic exchange of water into its different

stages is called Water Cycle.

5. The amount of water vapor present in the

atmosphere is called the Humidity.

Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

Answer:

In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression  

Explanation:

In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.

Answer:

The correct replication of DNA, followed by the correct division of DNA, to create two  identical daughter cells

Explanation:

The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.

Explanation:

Answer:

nCoV is often used to indicate a newly recognized coronavirus prior to definitive identification and classification. It is sometimes used in combination with the year of identification.

Explanation:

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Answer:

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Explanation:

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes.

DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Answer:

A niche is a role a species plays in the ecosystem. In other words, a niche is how an organism “makes a living.” A niche will include the organism's role in the flow of energy through the ecosystem. An organism's niche also includes how the organism interacts with other organisms and its role in recycling nutrients.
