Answer:
Thylakoid membranes
Explanation:
Photosynthesis is the process by which green plants make their own food using energy from sunlight, water and carbon dioxide.Photosynthesis takes place in organelles called chloroplast found mainly in the palisade mesophyll in the leaves of a green plants. The process occurs in two stages; light-dependent stage and light-independent stage.The light dependent stage occurs in the thylakoid membranes of the chloroplast, while the light-independent stage occurs in the stroma of the chloroplast.In cities, the area in which rainwater can seep into the ground is reduced.

A mouse with curled whiskers migrates from one forest community to another. She mates with other mice in the new community and passes the gene for curled whiskers to her offspring. This is an example of _____.
genetic drift
mutation
gene flow
natural selection
Answer:
Option C: Gene flow
Explanation:
Gene flow is the transfer of genetic variation from one population to another. It is the movement of genes from one population to another population. If the rate of gene flow is high enough, then two populations are considered to have equivalent allele frequencies.
Sometimes gene pools within populations can change because individuals leave that population or new individuals come in. Like water flowing in a river, genes can also 'flow' from one place to another.
For example:
A honey bee carrying pollen from one flower population to another.A caribou from one herd mating with members of another herd A blonde haired, blue-eyed family from Sweden moves to some Asian country where the children grow up, marry and produce offspring who now have the blonde-haired, blue-eyed alleles.Answer:

A compound forms when different substances chemically combine to form a new substance. D. all of these
the answer is all of these.
Answer:
D
Explanation:
All of these are true about mixtures and compounds.
Mixtures and compounds are both made of two or more different substances.
The key difference between mixtures and compounds is that a compound is a new substance that forms when other substances chemically combine. The new substance that is formed has different properties from the original substances.
A mixture is simply a physical combination of two or more substances. Some of the individual properties of the original substances are retained by the mixture.

Hummingbirds drink nectar from flowers robins eat plant seeds what does this reduce : a. Interspecific competition , be intraspecific competition ,c. cooperation ,d.mutualism
Answer:
Interspecific competition
Explanation:
Hummingbirds and robins are different species, so it is interspecific competition
Answer: a. Interspecific competition
Explanation:
The hummingbird drink the nectar from the flowers and robins eat plant seeds is the example of reduction of interspecific competition. The ecological niche of both of the species is different. An ecological niche can be define as the functional role an organism plays in an ecosystem.
In an interspecific competition, the individuals of distinct species compete for the same resource. This will lead to the extinction of any one of the species or decline in the members of the either of the species.
As the species of hummingbird is dependent upon the nectar and the robins are dependent upon the seeds as food therefore their will not be any interspecific competition among these species.
which sentence describes a possible impact of early hunter – gatherer societies on the environment?
a. cultivating too many plants drained the land of water.
b. introducing non-native species led to the extinction of some plants.
c. overhunting led to the extinction of large herbivores species.
d. reliance on fossil fuels polluted air, water, and land.
Answer:
Hi,
The correct answer is option (C) Overhunting led to the extinction of large herbivores species
Explanation:
Herbivores are those animal species that eat plants only.Hunters and gatherers depended on their hunting skills to obtain meat as a source of protein/food for their families.Most of the animals that were hunted were herbivores.Overhunting reduced the number of these species because the process was not controlled thus there was no time for the animals to increase in numbers in the natural process

The periodic table houses noble gas elements in group 18. These elements are highly stable and rarely react with any other elements. What is one possible reason for the stability of the noble gas elements?
Answer:
C.
Explanation:
In section 18 the elements are the most stable because they complete themselves without having to share electrons with other elements. Does that make sense?
Answer: Option (C) is the correct answer.
Explanation:
Elements of group 18 are also known as noble gases.
And, noble gases are the gases that have completely filled outermost shells.
For example, atomic number of neon is 10 and its electronic distribution is 2, 8.
As it has completely filled outermost shell hence, it does not need to either gain or lose an electron. Therefore, elements of group 18 are chemically inactive in nature.
Thus, we can conclude that one possible reason for the stability of the noble gas elements is that their outermost shell has the maximum number of electrons that it can hold.
Based on structure, in what way do DNA molecules differ from RNA molecules?
Answer:
Unlike DNA, RNA is almost always a single-stranded molecule and has a much shorter chain of nucleotides. RNA contains ribose, rather than the deoxyribose found in DNA (there is a hydroxyl group attached to the pentose ring in the 2' position whereas RNA has two hydroxyl groups). These hydroxyl groups make RNA less stable than DNA because it is more prone to hydrolysis. Several types of RNA (tRNA, rRNA) contain a great deal of secondary structure, which help promote stability.
Explanation:
What is a RNA molecule?
Well, RNA consist of aminoacids. An aminoacid is built up of three bases, which is a micture of a nucleoside (organic molecule), phosphatgroup and the base (A,T,G,C). This package is also called nucleic acid.
So RNA is built up the same way as DNA, but it's just a helix and not a duople-helix (DNA) and has got the base U instead of the base T. You can see that RNA is a molecule because its built up of molecules.
DNA is double-stranded and contains deoxyribose and thymine, whereas RNA is single-stranded, contains ribose, and has uracil instead of thymine.
Explanation:There are several key structural differences between RNA and DNA molecules. First, DNA is double-stranded, forming a double helix, while RNA is single-stranded. This means the DNA consists of two strands of nucleotides wound around each other, while RNA is just one strand of nucleotides. Second, the sugar component of the nucleotides in DNA is deoxyribose, while in RNA, it's ribose. This gives each molecule its name: DNA stands for deoxyribonucleic acid, and RNA for ribonucleic acid. Lastly, DNA and RNA differ in one of their bases: DNA contains the base thymine (T), while RNA contains the base uracil (U).

Plant roots can be fibrous or a taproot. When there is not enough water in
the environment some plants send their taproot further down into the soil in
search for water, while some with fibrous roots increase the density of their
root systems. What does this demonstrate?
OA) genetic mutation induced by the environment
OB) differentiation of vascular tissue in plants
OC) structural response to the environment
OD) alternation of generations in plants
Answer: i beleive you answer would be D hope this helps :)
Answer:
The best response to this question: What does this demonstrates, regarding two different types of plants, one with a taproot system and the other with a fibrous root system, who alter their aleady existing root system in order to respond to the changes in their environment, would be: C: structural response to the environment.
Explanation:
When talking about plants, and their roots, there are two great categories: the dicot plants, whose root system is known as a taproot, and the monocots, whose root system is fibrous. Each of these systems is separate and particular to each type of plants. They do not combine, and they are unique to each of the categories of plants (dicots, and monocots). However, according to the question, the plants are encountering a climate change, and water has become scarcer. In response to this change, each of the plants, the one with the taproot, and the one with the fibrous root, respond structurally by either enlarging their root further into the soil (taproot), or by sprouting further filaments in the original root system (fibrous root). This, then, shows a structural change and it can happen in plants when environmental changes, not necessarily constant, happen. The plant will only alter its genetic makeup if the changes in environment are continuous and they need deeper changes in the plant, in order to survive.

Examine the food web shown in figure 5-4. What would most likely happen to the organisms in this ecosystem if the algae began to disappear
If algae started to disappear from an ecosystem, it would negatively affect many organisms in the food web. There would be a reduction in food and oxygen for other aquatic organisms, potentially leading to their demise, and there could also be detrimental changes to the water's pH level.
Explanation:If the algae in a given ecosystem were to begin disappearing, it would have significant and potentially devastating effects on the other organisms in that system. Algae are primary producers, meaning they play a critical role in providing energy for the other organisms. When they photosynthesize, they convert sunlight into energy, which is then passed up the food chain when they are consumed by other organisms.
The absence of algae would result in the depletion of this primary source of energy, which would hinder the survival of the organisms that directly depend on them for sustenance, such as zooplankton. Over time, this effect would ripple through the rest of the food web, affecting secondary and tertiary consumers as their sources of food become scarce.
Furthermore, algae produce oxygen during photosynthesis, which is vital in aquatic ecosystems for the survival of fish and other aquatic animals. A reduction in algae would therefore lead to a decrease in oxygen levels, negatively affecting these organisms. The water's pH level could also be affected, as less carbon dioxide is being utilized by the algae for photosynthesis, leading to increased acidity and potentially harmful changes to the aquatic environment.

this image shows wind blowing a dust cloud across the Atlantic Ocean from Northern Africa. What type of movement does the image show?
please and thanks!
Answer:
B
Explanation:
Letter B
Answer:
The correct answer is option D, that is, suspension.
Explanation:
Suspension refers to the procedure that incorporates particles, that is, dust and fine dirt, which are less than 0.1 micrometers in diameter. Wind possesses the tendency to mediate these constituents over far off distances. It is possibly the most usual form of wind action and is also the easiest to determine. The suspension leads to sandblasting or abrasion. Abrasion is more robust near to the surface of the land and is less efficient with the objects present higher up the ground.

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
Explanation:
Answer:
The food webs is formed by several food chains. This is the relationship between the two systems.
Explanation:
Food web is a set of interconnected food chains. The food web represents the many relationships between organisms in an ecosystem.
Ecosystem is the place or environment in which mutual relations between all beings that inhabit it develop. The same living being inserted in an ecosystem can belong to different food chains, playing different roles.
It can feed another living being or serve as food. In the process, the food chains end up meeting and forming a food web.
Food chain is a sequence of living beings that are divided into producers, consumers and decomposers. In the food sequence, living beings feed on those who go before them in the chain, to then be eaten by those who are following, according to the hierarchy.

what is the function of a central vacuole
Answer:The central vacuole is a cellular organelle found in plant cells. It is often the largest organelle in the cell. It is surrounded by a membrane and functions to hold materials and wastes. It also functions to maintain the proper pressure within the plant cells to provide structure and support for the growing plant. (wiki.com) Hope this helps Hon!!
In plant cells, the central vacuole controls the concentration of water, maintains turgor pressure, and stores various substances.
In plant cells, the central vacuole has a number of important functions. It directs the cell's grouping of water in light of changing natural circumstances, chiefly through the upkeep of turgor pressure. The fluid inside the vacuole exerts this pressure, which helps keep the plant cell rigid and upright. For instance, if a plant is not watered, the concentration of water in the soil decreases, allowing water to enter the soil from the cytoplasm and central vacuole. The plant wilts as the cell wall is left unsupported as the central vacuole shrinks. Additionally, the bitter taste of the fluid within the central vacuole deters insects and other animals from eating the plant. In addition, the central vacuole stores pigments that can be used to color flowers and proteins that are found in the developing seed cells.What was the main commodity of the trans-Saharan trade route?

When a solvent equally disperses throughout a solution, what type of transport is this?
A. Facilitated diffusion
B. Active transport
C. Osmosis
D. Diffusion
The correct answer to the question is D. Diffusion, which is the process by which solutes spread from an area of higher concentration to an area of lower concentration until equilibrium is reached, without the need for external energy.
When a solvent equally disperses throughout a solution without the need for external energy and without the help of transport proteins, this process is known as diffusion. Diffusion is the movement of solute molecules from an area of higher concentration to an area of lower concentration until the concentrations are equal on both sides of the membrane. This process does not require energy, making it a form of passive transport. Facilitated diffusion, on the other hand, involves transport proteins but is still considered passive transport as it moves solutes down their concentration gradient. Therefore, the correct answer is D. Diffusion.

According to natural selection, long-spined cacti...
will survive longer, defend itsself better, and reproduce more often than short-spined cacti.
Hope this helped!
Answer:
The Cactus with long spines should evolve while the cactus with short spines should extinct.
Explanation:
Natural selection was a term used by Charles Darwin to talk about the natural evolution of the species and how they adapt to different environments. The individuals within a certain type of animal or plant had variations one from each other. Those variations that can adapt to the environment in which they are placed are the ones that evolve because they live longer than the others.
In this case, the cactus with long spines will survive because it protects itself from animals better than the cactus with short spines. This last will extinct because eventually, animals will eat all of them.
