None of the options given are only found in animal cells.
Explanation:
The plant and animal cell differ only in three more organelles in plant cells. The presence of cell wall, vacuoles and plastids in plant cell make it different from the animal cell.
The options of organelles provided are common to both animal and plant cell.
The correct answer is "Lysosomes".Chloroplasts are specialized organelles in plant cells responsible for photosynthesis, and they contain the pigment chlorophyll for absorbing light energy. In contrast, lysosomes, containing digestive enzymes, are organelles found predominantly in animal cells.
In plant cells, chloroplasts are essential organelles responsible for photosynthesis, which is the process of converting light energy into sugars using water and carbon dioxide. This process creates glucose and molecular oxygen, serving as a foundation for most ecosystems' food chains. Chloroplasts contain chlorophyll, a pigment that absorbs the sun's energy, vital to this process, and they are only found in eukaryotic cells of plants and algae. On the other hand, organelles such as lysosomes are found predominantly in animal cells. Lysosomes are special vesicles that contain enzymes designed to digest and break down various biological molecules.

10. Cloud droplets form and grow as water vapor condenses onto hygro-
scopic condensation nuclei. Research has shown that the maximum
radius for cloud droplets is about 0.05 millimeter. However, typical
raindrops have volumes thousands of times greater. Explain how cloud
droplets become raindrops.
Answer:
According to collision- coalescence theory, formation of raindrop from cloud droplets occurs when cloud droplets collide and coalesce or stick together.
Explanation:
The only significant difference between a raindrop and a cloud droplet is that a raindrop consist of a velocity that is non-negligible during the fall.Larger droplets having higher terminal velocities fall faster and collide with smaller droplets. Often the cloud droplets stick together and coalesce to form a larger droplet. This starts a chain reaction where these bigger droplets fall even rapidly, collide with the other droplets in their path and merge with these droplets.Ari drew a diagram to show organisms in an ecosystem.

A group of runners gathers every week to train for long-distance runs. Several students in your anatomy class are part of this group. Your classmates are curious about the physiological changes that occur with exercise. You do a little research in class and find several changes occur as exercise begins. Which of these correctly lists the changes that occur as exercise begins?
A) increased vasodilation, increased cardiac output, increased venous return
B) decreased vasodilation, decreased cardiac output, decreased venous return
C) increased vasodilation, decreased cardiac output, increased venous return
D) increased vasodilation, increased cardiac output, decreased venous return
Increased vasodilation, increased cardiac output, decreased venous return occurs during exercise.
Option D.
Explanation:Exercise is a condition where the body works more than normal, leading to more consumption of nutrients and oxygen in the active muscles of body. The exercise also produces a lot of carbon dioxide in the muscles.
The increase in carbon dioxide and the need of oxygen and nutrients in the muscles lead to the para sympathetic stimulation which leads to the increase in vasodilation. This increase in vasodilation leads to reduced peripheral resistance which in turn reduces the venous return.
While, heart has sympathetic stimulation which causes the heart rate to increase and as a result cardiac output to increase too. But due to reduced venous return, the stroke volume increases up to a certain limit from where it remains still, because of the reduced blood in heart.

A falcultative anaerobic organism is able to perform aerobic respiration in the presence of oxygen and fermentation in the absence
of oxygen. An example of a falcultative anaerobic organism is brewer's yeast, which is used in the production of alcoholic
beverages. If sealed in a vessel containing oxygen gas, water, and sugar (glucose), the yeast will eventually deplete the oxygen
gas. As long as glucose is available, however, the yeast can still survive.
Brewer's yeast use oxygen preferentially because???
Please answer quick
Answer:
The answer is B. Hope this helps!
Brewer's yeast use oxygen preferentially because aerobic respiration is more efficient than fermentation.
What do you mean by fermentation?Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Fermentation is the process of sugars being broken down by enzymes of microorganisms in the absence of oxygen. Microorganisms such as bacteria and fungi have unique sets of metabolic genes, allowing them to produce enzymes.
Both types of fermentation require two primary components, a sugar supply and a bacterial culture; alcohol fermentation use forms of yeast, while lactic acid fermentation normally relies on lactic acid bacteria.

The decay of uranium isotopes is used to provide what information about Earth's history?
The decay of uranium isotopes is used to provide information about the age of Earth.
Explanation:Isotopes of Uranium U-232, U-233 , U-234 , U-235 , U-236 , U-238 are used as fuel in nuclear reactors or as explosives for nuclear weapons. Uranium 238 is not very radioactive and it constitutes for nearly 99.3% of natural uranium on Earth and has the longest lifetime: its period is 4.5 billion years, about the age of Earth.
Use of radiometric dating techniques help in defining the age of substances (natural or man-made) using the known decay rates of radioactive elements. Each element has an individual decay rate and half life time.
Two Uranium isotopes (U-238 and U-235) are used for radiometric dating. Both the isotopes have different decay rates and half life period. Both are unstable and radioactive. Since two different isotopes produce two different decay clocks (one as a reference to other), it is beneficial in accurately determining the age of samples. The age of earth (rocks or other natural elements) can be easily determined using Uranium isotopes.

Which of these is an agent of abrasion?
A. Rock pieces
B. Acid rain
C. High pressures
D. Plant roots
Answer:
A. Rock pieces
Explanation:
Abrasion is the breaking down and wearing away of rock material by the mechanical action of other rocks. Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. None of those are agents of abrasion. But Rock pieces are a result of abrasion.
Rock pieces act as an agent of abrasion, which is a process of mechanical weathering caused by physical forces such as gravity, water, wind, or ice. Option A is correct.
Among the options given, rock pieces are an agent of abrasion. Abrasion is a type of mechanical weathering where one rock bumps against another, causing the surfaces to wear down over time. This can happen due to gravity, moving water, strong winds, or glacial movements.
When pieces of rock are moved by water or wind and collide with other rocks, they cause the surfaces to erode. For example, the ice in glaciers also cause abrasion when pieces of rock embedded in them scrape against the rock below.
Hence, A. is the correct option.

The strands are joined together by the hydrogen bonding between the nucleotide bases. Hence, the structure Y is that of a DNA.
Winds in our atmosphere are created as a result of which of the following processes?
A. Energy that is absorbed in the atmosphere
B. Gravitational attraction from the moon
C. Density of the air particles in the atmosphere
D. Uneven heating of the air in the atmosphere
Answer:
The correct option is D) Uneven heating of the air in the atmosphere
Explanation:
Wind can simply be described as air which is moving or which is in motion. The uneven heating of the Earth's surface caused by the sun is the reason why winds occur. The difference in pressure of one area to another area causes the air to move and cause wind. The air tends to move from an area of higher pressure to an area of lower pressure and such is the movement of the wind.
Explain how geographic isolation can affect
evolution.
NEED HELP NOW!!
Answer:
Geographic isolation stops the exchange of genetic material between the two populations. ... Differences in climate and food sources can create selective pressures unique to each population. Eventually, the two populations might become different species, but not always.
Final answer:
Geographic isolation triggers allopatric speciation by physically separating populations, leading to genetic divergence and potentially the evolution of new species. It often results in the emergence of endemic species uniquely adapted to localized environments.
Explanation:
Geographic isolation affects evolution by preventing populations of the same species from interbreeding. This process, known as allopatric speciation, can be initiated by various events, such as the formation of a river or valley, a group of organisms becoming stranded after migrating, or seeds being carried to an island by the wind or ocean currents.
Once populations are isolated, there's no genetic flow between them. Genetic divergence may occur as natural selection acts differently on the populations or as a result of genetic drift. These changes can eventually lead to reproductive incompatibility, meaning that even if the two populations come into contact again, they can no longer interbreed and have thus evolved into separate species.
Endemic species, which are found only in specific geographic locations, are often the result of long periods of geographic isolation that have allowed them to develop unique characteristics catered to their particular environment, isolated from the gene pools of their species located elsewhere.
