The image shown is an artist's drawing of a nerve cell. The overall shape and structure of a nerve cell is unlike most other types of cells. Which particular function of nerve cells is facilitated by the unique shape of the cell? A) communication B) digestion C) metabolism D) transportation

Answers

I would say communication, as neurons transmits messages from one part to another part of the body
Answer:

The correct answer is option A which is communication.

Explanation:

Nerve cells have a different structure from other types of body cells due to a different function.

The function of the nerve cell is to communicate the nerve signals in the nervous system from the receptor to the brain and from the brain to the effector.

The nerve cell has a cell body and an extended fiber type area known as the axon.

This specific structure is suitable for the transport of nerve impulse from one end to another which is for the communication between two nerve cells.

What type of reproduction shuffles the genes

Answers

Sexual, because there are two parents instead of one
Sexual reproduction allows for the shuffling of genes in organisms. Sexual reproduction requires two parents and is the preferred choice of reproduction of most higher forms of plants and animals. Sexual reproduction is the formation of an organism from the uniting of two different sex cells; a sperm and an egg. 
 Asexual reproduction on the other hand is the formation of an organism from a single parent.

After a volcanic eruption has covered an area with lava, which of the following is the most likely order of succession in the re-population of the area? * lichens → grasses → shrubs → trees mosses → grasses → lichens → trees grasses → trees → mosses → lichens shrubs → grasses → trees → lichens

Answers

The choices for this question are:
A lichens →grasses →shrubs →trees 
B mosses →grasses →lichens →trees 
C grasses →trees →mosses →lichens 
D shrubs →grasses →trees →lichens

The correct answer is A. Lichens are able to survive in very harsh environments and would therefore be a suitable pioneer. Grasses would be suitable to succeed lichens as the lichens break down the larva rock into soil. After further breaking down of rock into soil by grass, shrubs will start to grow and these will be succeeded by trees as the ecosystem approaches maturity. 

After a volcanic eruption, the order of succession in the re-population of the area is following:

Lichens → grasses → shrubs → trees.

The correct option is A.

Ecological succession

The process of change in the species structure of an ecological community over time is known as ecological succession.Lichens are considered a self-sustained miniature ecosystem of themselves.They can grow themselves in any condition.After lichen, grasses can be grown and, then shrubs and trees.

Thus, the correct option is (A).

Which of the following adaptations best helps desert plants survive? Wide leaves to lose water Spines to reduce water loss Smooth stems to increase transpiration Thin leaves to reduce the ability to store water

Answers

The answer is 'spines to reduce water loss'. Spines are in effect a specialised form of leaf. Obviously, spines have a much reduced surface area compared to a leaf, thereby drastically reducing evapotranspiration. The spines also have an important protective function for the plant. Other adaptions by desert plants would include retaining water (such as succulents), a waxy cuticle on leaves to reduce water loss and closure of the stomata to reduce water loss.

Explanation:

If the producer contains 6000 of energy how much energy will the secondary consumer contain

Answers

The proportion of energy transferred from one trophic level to the next is known as trophic level transfer efficiency or ecological efficiency. The Ten Percent law states that 'net production at one trophic level is generally only 10% of the net production at the preceding trophic level'. In this example, the producer contains 6000 units of energy. 10% of this will be transferred to the primary consumer, i.e. 600 units. In turn, 10% of this energy will be transferred to the secondary consumer i.e. 60 units.

Secondary consumers would have roughly 60 units of energy if the producer contains 6000 units, based on the approximate 10% energy transfer between trophic levels in an ecosystem.

The question concerns the amount of energy contained by a secondary consumer if the primary producer has 6000 units of energy. In ecology, energy transfer between the trophic levels is typically about 10%. Using studies by Howard T. Odum on the Silver Springs ecosystem, we know that the primary producers generated 20,819 kcal/m²/yr. The primary consumers, in turn, generated 3368 kcal/m²/yr, secondary consumers generated 383 kcal/m2/yr, and tertiary consumers only 21 kcal/m²/yr. By applying the 10% rule, we can estimate that if primary producers have 6000 units of energy, the primary consumers would have approximately 600 units of energy, and the secondary consumers would have roughly 60 units, considering each level consumes about 90% and only passes on 10% to the next level.

Which of the following body parts has smooth muscles?

Biceps
Heart
Triceps
Stomach

Answers

the stomach has smooth muscles

The stomach has smooth muscles (involuntary muscles). Therefore, option D is correct.

What are smooth muscles?

Smooth muscles are also known as involuntary muscles. They are a type of muscle tissue that is found in the walls of organs, blood vessels, and other internal structures in the body.

They are called "smooth" because they lack the striations or bands that are present in skeletal and cardiac muscle tissue.

Unlike skeletal muscle, which is under voluntary control, smooth muscle is controlled involuntarily by the autonomic nervous system. This means that we cannot consciously control the contractions of smooth muscle, which happen automatically in response to various stimuli. They are responsible for many involuntary movements in the body. Therefore, option D is correct.

Judy kept 250 grams of juice in the freezer. What is most likely the mass of the frozen juice formed and why?

250 g, mass remains same during physical change of freezing
500 g, mass of ice is twice the mass of juice
250 g, mass is conserved when matter is destroyed to form ice
200 g, mass of frozen liquid is less than mass of the original liquid

Answers

The answer is simple. It stays at 250 grams, because when the juice freezes, the volume shrinks down due to the amount of movement they are making, but the mass never changes. It obviously can't be the third answer 250 grams because the mass is conserved when the matter is destroyed to form ice. You can't destroy or create matter, as we can tell by the laws of conservation of matter, matter cannot be created nor destroyed. And there is no way that the mass would double in size.

Answer: Option A

Explanation:

The juice of 250 grams will be the same in case of ice this is because the mass of the liquid will not change when there is a physical change in the state  of matter.

The change in state of matter does not changes the mass of the substance. IF 250 grams of water is kept inside the freezer to get converted into ice, then the 250 grams of liquid will be 250 grams of ice.

hence, option A is correct.

its B because Arteries deliver oxygenated blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place.

One similarity between the lungs and capillaries is that they are both involved in gas exchanges.

What do you mean by Capillaries?

Capillaries may be defined as a network of blood vessels that supplies blood as well as oxygen throughout the body.

Both the lungs and the capillaries are actively involved in the exchange of gases in and out of the body. The capillaries are connected to the walls of the alveoli where oxygen and carbon dioxide diffuse. Carbon dioxide is exhaled outside by the lungs, while the oxygen is attached to the RBCs and travels to the heart.

Therefore, one similarity between the lungs and capillaries is that they are both involved in gas exchanges.

in humans , the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). a female who is homozygous for long eyelashes and a male with short eyelashes have a child. identify the phenotype and genotype ratio of the offspring.

Answers

Homozygous means there are two dominant or two recessive genes. In the case of the female, it is dominant, so her genotype is LL. In order for the male to have short eyelashes, he must be homozygous recessive, or ll.
When you cross LL by ll, you will end up with Ll, Ll, Ll, Ll, or 100% heterozygous dominant genotype. The genotype ratio of the offspring is 1:1.

Hope this helps =)

When a homozygous female with long eyelashes (LL) and a male with short eyelashes (ll) have children, all offspring will have long eyelashes with a genotype of Ll, leading to a phenotype ratio of 100% long eyelashes and a genotype ratio of 100% heterozygous (Ll).

In humans, the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l). A female who is homozygous for long eyelashes (LL) and a male with short eyelashes (ll) will have children. All of the offspring will have one dominant allele for long eyelashes from the mother and one recessive allele for short eyelashes from the father, resulting in a genotype of Ll for each child. Since the long eyelash allele is dominant, all of the children will exhibit the phenotype of long eyelashes. Therefore, the phenotype ratio of the offspring will be 100% long eyelashes, and the genotype ratio will be 100% heterozyous (Ll).

The incissors of a humand and a rat at a really much bigger than them of another animal. Thats why they can share the same diet.

According to the branching tree model, Jaws would most likely be located between points 1 and 2. As a result, the perch, frog, pigeon, and other species would not have developed until after the common ancestor and before the derived shared property of jaws.

How did the body of our ancestors' teeth develop throughout time?

A crucial stage in the evolution of vertebrates, including humans, was the evolution of jaws in the bodies of our ancestors. Gnathostomes, the earliest jawed vertebrates, descended from jawless fish and first showed up in the fossil record about 420 million years ago.

Early jawed vertebrates were able to diversify their meals and widen their range of habitats thanks to the evolution of new feeding techniques like biting and chewing. This development also facilitated the development of more intricate teeth, which further enhanced their capacity to consume a range of food sources.

Thus, according to the branching tree model, Jaws would most likely be located between points 1 and 2.

B. Bacteria cells are larger than seaweed cells.

C. Seaweed have systems, while bacteria do not.

D. Seaweed are multicellular, while bacteria are not.

Answers

D) Seaweed are multicellular, bacteria are not

The correct answer is option D.Seaweed are multicellular and belong to the domain Eukarya, whereas bacteria are unicellular and belong to the domain Bacteria. Seaweed have eukaryotic cells with a nucleus, while bacteria have prokaryotic cells without a nucleus. Thus, the main difference is that seaweed are multicellular, while bacteria are not.

Seaweed and bacteria have distinctly different cellular structures due to their classification into different domains of life. Seaweed, which are large, multicellular algae, belong to the domain Eukarya, meaning they are composed of eukaryotic cells. These cells have a nucleus and membrane-bound organelles.

On the other hand, bacteria belong to the domain Bacteria and are made up of prokaryotic cells, which lack a nucleus and membrane-bound organelles. Additionally, bacteria are typically much smaller in size compared to the larger, multicellular seaweed.

Therefore, the correct answer to the question is: D. Seaweed are multicellular, while bacteria are not.
