10 pounds of seal for a killer whale to gain one pound (10:1). how many pounds of seal will it have to eat to gain 20 pounds of killer whale?

Answers

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.

The water hyacinth is an invasive species that can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity. This situation demonstrates _______. a. how migratory patterns change in response to alterations in an ecosystem b. the effects of symbiosis c. the effects of local evolution or migration on an ecosystem d. how changes in biodiversity impact an ecosystem

Answers

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:

Why is the structure of a
nucleosome so important?

Answers

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.

7. (True Story) In Denmark, a husband and wife who had been unsuccessfully trying to have a
baby went to a fertility clinic. Sperm and eggs were collected from father and mother, and
combined in a petri dish, creating several "test-tube babies". These babies were implanted in the
mother and 9 months later she ſlelivered twins, one with lightly pigmented skin and one with
darkly pigmented skin. Because this seemed strange, a DNA test was conducted and it was
found that both children were related to the mother, but only the light skinned child was related to
the father. How can this be explained? (Hint, there was no infidelity)

Answers

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.

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

What is Infrared radiation?

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.

Why does DNA need to be replicated

Answers

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.

I WILL GIVE BRAINILEST FOR THE BEST ANSWER DONT BE MAD IF U DONT GET IT PLS Read the text from the following website: www.growingnation.orgA Growing NationAfter the American Revolution, the newly formed United States realized that it lacked room to grow. The states created in the Declaration of Independence in 1776 were limited in size. As the population increased, more people were competing for the same amount of land. Consequently, land became more expensive, and overcrowding became an issue. The thirteen states were bordered by the Atlantic Ocean and the territories of other nations. If the United States was going to have a future, it needed to increase its territory.President Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land. He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States.USA is shown and different areas are highlighted. The east coast region is highlighted first and shows 1776, the middle east is highlighted next and shows 1803, the mid north and all of the east is highlighted third and 1821 is highlighted. Then all of the middle and east areas are highlighted and 1845 is shown. Next the north west area is highlighted and 1846 is shown. Then the south west area is highlighted and 1848 is shown. Last, the south part of Arizona is highlighted and shows 1853.The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict. The United States purchased Florida from Spain with the Florida Purchase Treaty of 1821. Instead of paying Spain a set amount, the United States would pay the $5 million Americans claimed were owed to them by Spain. After Texas declared independence from Mexico, it was annexed by the United States and became an official state in 1845. Another land controversy occurred between Great Britain and the United States, as both countries claimed the Oregon region. The dispute was settled in the 1846 Oregon Treaty, which separated the countries by the line of the 49th parallel. Mexico refused to let the United States buy California and New Mexico, so the two countries eventually went to war. Because the Americans won the war, the United States was able to buy lands in the Southwest in 1848. The United States paid Mexico $10 million for an area of land in the Southwest in the 1853 Gadsden Purchase, stretching its borders from sea to sea.(the map is the text feature btw)According to information in the text feature, in what year did the United States officially obtain land with access to the Pacific Ocean? a1821 b1845 c1846 d1848 Can someone please help me with this one Which statements are true about the expression that y +92 Choose ALL that apply. 1.
