Answer:Organizing changes to the shape of the cell membrane that allow the membrane to "pinch" in two during cell division.

Ensuring that chromosomes are properly distributed to daughter cells by creating and shortening mitotic spindle fibers.

Overseeing other important changes to cell membrane shape, such as those seen in phagocytosis.

Explanation:

he main function of the centriole is to help with cell division in animal cells.  The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis).

Answer:

D human because decomposer are mainly fungi and bacteria,producer are plants, consumers are every organism that eats something else it include herbivores, carnivores(animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses)

Humans play the role of a consumer in a food web as they eat other organisms to gain energy and nutrients. They do not play the role of producers or decomposers. The term 'human' alone does not specify a role in a food web.

In the context of a food web, we humans play the role of a consumer. Consumers are organisms that eat other organisms to gain energy and nutrients. We certainly fit into this category as we eat both plant (producers) and animal species (other consumers).

Producers are incorrect because they are typically plants that make their own food through photosynthesis which humans do not do. Decomposers are also incorrect as they break down dead or decaying organisms, a role humans don't play in the food web. Lastly, while 'Human' is within the options, it is too broad a term for this question as it doesn’t specify the role that humans play.

The statement 'Irrigation at night using recycled water and drip sprinkler irrigation are ways not to conserve water' is b. false.

Both irrigation at night using recycled water and drip sprinkler irrigation are methods that conserve water.

Drip irrigation is a highly efficient method of delivering water directly to the crop roots, hence minimizing water wastage through evaporation and runoff.

This practice is extensively used in places like Israel, which are known for their advanced water conservation techniques. Recycled water, often referred to as grey water, is treated wastewater that can be reused for agricultural purposes.

Irrigating at night significantly reduces the amount of water lost to evaporation compared to daytime irrigation. As a result, more water reaches the plants, further enhancing efficiency.

Answer:

1. The cells of eucaryotes are characterized by the presence of a nucleus and membrane-bound organelles. Bacteria, on the other hand, do not possess a nucleus or membrane-bound organelles.

2. As bacterial cell walls are made of peptidoglycan (protein and sugars), and archaeal cell walls are composed of polysaccharides (sugars). I would add a lysis solution that separates the cell wall and integral molecules. Then, I could use High-performance liquid chromatography to quantify the chemical composition differences of both walls.

Explanation:

1. The cells of eucaryotes are characterized by the presence of a nucleus and membrane-bound organelles. Bacteria, on the other hand, do not possess a nucleus or membrane-bound organelles.

2. Both archaea and bacterial cells lack membrane-bound organelles and nucleus, but they both possess a cell wall. Therefore, if I realize that the cell is definitely a prokaryote and not a eukaryote, then, to determine if it is from an archaeon or bacterium, I would analyze the integrity of their cell walls as bacterial cell walls are made of peptidoglycan (protein and sugars), whereas archaeal cell walls are composed of polysaccharides (sugars).

I could add a lysis solution that separates the cell wall and integral molecules. Then, I could use High-performance liquid chromatography to quantify the chemical composition differences of both walls.

Also, the majority of archaea cannot be cultured within the laboratory setting. So that could also work as another method, except it wouldn't be as reliable as the others.

Answer:

When a star expands, the surface of the star becomes cooler as well as redder. Hence, forming the red giant.

Explanation:

If all the hydrogen which is present in a star gets fused into helium then an increase in the core temperature can be seen along with the core contractions. As a result of these core pressures and the core temperatures, the helium gets fused into carbon through a process known as the triple alpha process. As a result, the star begins to expand whereas its surface becomes cooler and redder which leads to the formation of red giant.

ECOLOGICAL SUCCESSION

A change in plant communities over time is called succession, which is an important concept in ecology. Succession can be categorized into primary and secondary.

Any change in plant communities over time is called succession. This is a significant concept in ecology which describes how the structure of a biological community evolves over time. Succession can be primary or secondary. Primary succession occurs in an area that has never previously been colonized by life, like a new volcanic island, while secondary succession happens in areas where a community previously existed but was removed or disturbed, such as after a forest fire.

Answer:

Fewer resources

Explanation:

With fewer resources, there won't be many competitions with a species population increasing. And not only that but without any resources, there won't be any "competitors" left to compete.

Competition among species is defined as the rivalry for the shortcoming of resources like food, shelter, and water. The competition among species can be reduced by fewer resources.

The correct answer is:

Option C. fewer resources

Competition is defined as the rivalry among the organisms belonging to different ecological niches for resources.

The species when competing for the limiting resource will cause the overlapping of the ecological niche. This will lead to evolutionary changes in the organisms.

The selection of better-suited organisms to the environment will have a higher chance of survival and adapt to utilize the resources left available.

With fewer resources, the competition among species decreases as there won't be competitors available.

Therefore, option C is correct.

Hence, the correct term for nutrient deficient people is malnutrition.

Answer:

The correct option is Option C i.e. Herbicide-resistant crops may grow out of control and become weeds.  

Explanation:

1. The herbicide resistance is a genetic character that is introduced into the plant with help of genetic engineering.

2. Now crops are not sexually reproduced. New seeds are planted every season. So chance of losing the herbicide resistance is less.

3. The risk of weeds becoming herbicide resistant is there even with genetic engineered crops.

4. Cross-pollination between two different species doesn’t occur generally.

5. But if these plants are not killed by any herbicides, they themselves can grow too fast as weeds.  

Answer:

A. Cross-pollination could cause the crops to lose their herbicide resistance.

Explanation:

Herbicide resistance is the acquired capacity of plants to endure and imitate following introduction to a portion of herbicide typically deadly to the wild kind. Herbicides don't actuate opposition in weed species, rather they basically select for resistant individuals that normally happen inside the weed populace.

Herbicide resistance, communicated by a recessive allele, advances and spread generally gradually as the dominant heterozygotes and homozygous prevailing phenotypes are dispensed with by use of the herbicide to which resistance created.

This is truthful for cross-pollinating species, be that as it may, in exceptionally self-pollinating species, the resistant alleles can spread rapidly as selfing increments the recurrence of homozygotes to the detriment of heterozygotes.

Ciliated epithelial cells. Cilia are tiny hair like structures on the surface of the cell. The hairs sweep hair, mucus, trapped dust and bacteria up to the back of the throat where it can be swallowed.

Cartilage is a soft, spongy connective tissue. The bones in a synovial joint are connected by ligaments. Ligaments are a type of connective tissue and are tough, fibrous and slightly elastic. They connect bone to bone and help keep the joint together.

Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions

Nervous tissue is composed of three main parts: nerves, the spinal cord and the brain. The primary function of nervous tissue is to receive stimuli and send the impulse to the spinal cord and brain. The brain sends back a response to the muscles via the nerves.

Epithelial tissue covers and lines surfaces, connective tissue binds cells and organs, muscular tissue moves the body, and nervous tissue transmits signals.

Epithelial tissue is composed of sheets of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands. Its functions include protection, absorption, secretion, and selective permeability.

Connective tissue binds cells and organs together. It provides support, protection, and integration of body parts. Examples of connective tissue include bones, cartilage, blood, and adipose tissue.

Muscular tissue is involved in movement. There are three types of muscle tissue: skeletal muscle that is voluntary, smooth muscle that is involuntary, and cardiac muscle that is found in the heart.

Nervous tissue is responsible for transmitting electrical signals throughout the body. It enables communication between different regions of the body through nerve impulses.

An ecosystem is a complex network of interacting organisms and their environment. It includes a food web that illustrates the transfer of energy between producers, consumers, and decomposers. Ecosystems are vital for maintaining ecological balance and the flow of nutrients.

The term for a complex group of organisms that are connected and interact with one another is an ecosystem. In an ecosystem, different populations of organisms coexist and form a community that interacts not only among themselves but also with the physical environment. This level of ecological study helps us understand the intricate connections that allow diverse life forms to thrive together. For example, in an ecosystem, a food web illustrates how energy and nutrients flow from one organism to another, demonstrating the dependence and relationships between producers, consumers, and decomposers.

Each organism plays a specific role within this system, contributing to the broader biogeochemical cycles that sustain life on earth. The primary producers, such as plants and algae, harness energy from the sun to create biomass through photosynthesis. This biomass serves as the foundation for all other organisms within the food chain, with consumers and decomposers relying on it for their survival. The complex interactions and feedback mechanisms within ecosystems are essential for maintaining balance and resilience against environmental changes.

Answer: protons

Explanation:

Changing the number of protons would change it into an atom of a different element.

Hello! Your answer is protons.

There are three main parts of any atom. The proton, neutron, and electron. The proton and neutron form the center of the atom, or the nucleus, while the electrons float around them.

The protons determine the element. The number of protons is the atom's atomic number. For example, if there were 6 protons, the element would be the one with an atomic number of 6, or carbon. If there was just one, it would be hydrogen as that has an atomic number of 1.

When you change the number of neutrons, you get isotopes. This changes the atomic mass, as neutrons' main impact is mass. This also can mainly change stability. When you change the number of electrons, you change the charge of an atom. Electrons' main purpose is to bond + charge the atom. Electrons don't weigh much, they barely weigh anything. They instead give a negative charge to an atom (while the proton gives a positive)
