Second one.

"Unlike the water in lakes and ponds, the water in rivers and streams flows."

Answer:

c

Explanation:

Competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means. Therefore,option (C) is correct.

Cattle, like all living organisms, require a consistent supply of water in order to survive. In the passage, it is mentioned that the streams in the cattle's area are dry, which means that there may be limited access to water in this area. Cattle, also known as cows or bovines, are large, hoofed mammals that are domesticated for their milk, meat, leather, and other products. They are typically raised on farms or ranches, and are known for their docile and gentle nature. Cattle are herbivores, and are typically fed a diet of grass, hay, and other plant materials

As a result, the cattle may have to compete with one another for access to water, as it is a basic necessity for survival. In this situation, competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means.

Explanation:

Answer:

D. treeless, permafrost, cold dark winters

Explanation:

The correct answer would be D

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.

The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.



Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.

Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.

Therefore, option (D) is correct.

Answer:

A. Tapeworm in an intestinal tract.

Explanation:

This symbiotic relationship is parasitic because the tapeworm causes harm to the host. Tapeworms feed off the nutrients the host consumes, thus making the host sick.

Not parasitic:

Bees transport pollen from flowers back to the nest to feed the young bees, but pollinate female flowers as well which keeps the flower population alive.

Pilot fish swim under sharks to keep other prey from eating them, and the shark do not eat eat the pilot fish.

Birds eating the insect of the back of a hippopotamus keep the hippo clean and parasite-free as well as feeding the birds.

The presence of tapeworm in intestinal tract is considered parasitic. Thus, the correct option is A.

Symbiotic relationships refers to the association between two two organisms belonging to different species. There are three types of symbiotic relationships which are mutualism, commensalism and parasitism.

In mutualism, both of the organisms involved are benefited from the relation.

In commensalism, one of the organisms involved is benefited and the other is neither benefited nor harmed from the association.

In parasitism, one of the organisms involved is benefitted and the other one is harmed from the association.

As in the relationship between tapeworm and human, tapeworm is benefited but the human involved is harmed. Thus, it is a parasitic relation.

Thus, the correct option is A.

Answer:

Explanation:

Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.

Answer:

Since you haven't attached the illustration for finding out the amino acid sequence from the mRNA sequence from, I'll explain the general principle for it.

The mRNA represents the code for translation into specific amino acids which will form the protein. A group of three bases, a triplet code, is referred to as a codon. The tRNA is responsible for recognizing the codon and matching the anticodon that will attach to the mRNA and generate the chain of appropriate amino acids.

Explanation:

Skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

Polygenic inheritance is defined as a type of heredity where the trait is created by the interactions of many genes, as opposed to monogenic inheritance where the phenotype is created by the expression of just one gene.

When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.

Multiple gene or multiple factor inheritance are other names for polygenic inheritance.

The some of the characteristics are since epistasis is not at play, the expression of one gene is not obscured by the existence of the other genes. There are no dominant or veiled genes; the gene involved in polygenic inheritance is either contributing or non-contributing.

Thus, skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

Explanation:

Answer:

C) presence of a nucleus

Explanation:

A is incorrect because all cells have a cell membrane

B is incorrect because a flagella does not determine whether or not the cell is eukaryotic or prokaryotic

D is incorrect because a cell wall is used to differentiate an animal cell from bacteria, archaea, fungi, plants, and algae cells

Only eukaryotic cells have a nucleus

Hope this helps :) (maybe mark me brainliest?)

Presence of a nucleus would identify this cell as eukaryotic cell. Therefore, option (C) is correct.

Eukaryotes are organisms with nuclei in each of their cells. Eukaryotes include all animals, all plants, all fungi, and many unicellular creatures. They are a part of the Eukaryota or Eukarya group of organisms, one of the three categories of life.

A cell's genetic material is housed in a central chamber that is encircled by membrane and is known as the nucleus. compartments with specific functionalities that are membrane-bound and floating in the cytoplasm.

Answer:

We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.

Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Answer:

Deforestation on rainforests and other natural environments can have a devastating effect on the whole world. First, it leads to the loss of many animal and plant species, decreasing the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. Deforestation also has a negative effect on climate change, as trees are able to absorbe an enormous amount of greenhouse gas emissions. Without them,  the greenhouse effect is amplified, worsening climate change.

ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.

ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.
