Flowers are an important part of __________ reproduction in strawberry plants. A) abiotic B) asexual C) budding D) sexual

Answers

Answer:I had this question on usa test prep its b

Explanation:

Strawberry plants can reproduce several ways. A strawberry plant's main stem is called a crown. This crown produces spirals of leaves, runners, and flowers. The flowers become the strawberries that we love to eat. When days are long and warm, the plant produces runners. Runners are offshoots of the parent plant, sometimes called stolons. These runners are stems growing out from the crown along the ground. The runners grow roots and along the runner, "daughter plants" can develop. Most commercial strawberry growers use runners to produce new plants.

Where does photosynthesis generally occur?

Answers

To answer your question it uselly exerts in PLANTS because they take sunlight and the use it to make food hope this helps

Final answer:

Photosynthesis primarily happens in the chloroplasts of plant cells, especially in the leaves. However any green part of the plant containing chloroplasts can participate in photosynthesis.

Explanation:

Photosynthesis generally occurs in the chloroplasts of plant cells. These are the organelles where light energy is converted into chemical energy, the process we know as photosynthesis. The chlorophyll molecules, which give plants their green color, are located within the thylakoids of the chloroplasts and play a crucial role in capturing sunlight for photosynthesis.

Chloroplasts are typically found in high concentrations in the plant's leaves, which are themselves organized to maximize light absorption. This is why the leaves are usually the main site for photosynthesis in a plant, but photosynthesis can also occur in any green parts of the plant, including stems and un ripened fruit, meaning any parts where there are cells containing chloroplasts.

What can happen if an organism's population gets too big?

Answers

Greetings!

There are many bad consequences that may occur if a population becomes to large/over-sized. 

Here are a few examples:

~Shorter Supply of food and water. 

~Limited Shelter

~More predation 

These are only a few things that may happen.

Rarely, however, do we see a population get to big for its environment. Normally, nature seems to balance itself out. Even us, humans, have not become to many for the Earth we live on.

However, if over-population were to occur, then there are licensed hunters that may be put in charge, to take care of the situation. 
If an organisms population gets too big and exceeds the carrying capacity, a lot of consequences may happen, such as fighting for food, resources, but eventually some must die off.

If the population is over the carrying capacity, resources such as land, food, or water must be limited and organisms must fight for it in order to survive. And who wins? The ones that have a favorable characteristic. They survive while others die. When the number of organisms that die exceeds the number that is born, this is the death phase in a population. Death phase is very common if the initial population gets too big.

Which of the following is an example of a predator-prey relationship? birds feed off the flies that swarm around buffalo a rabbit population is the main source of food for a certain fox population ticks can attach and live on the blood of bison in their attempt to obtain nectar from blooms, bees transfer flower pollen from site to site]

Answers

'A rabbit population is the main source of food for a certain fox population' is the correct answer, because the first example shows a mutualistic relationship, the third shows a parasitic relationship, and the final one shows another mutualistic relationship. 

How are history and geography linked

Answers

Geographical advantages produced a more well-developed society. Egypt, for example, had great natural barriers such as deserts and cataracts. Due to their good geographical location, they created a more advanced civilization. Thus, geography is linked to history because they both work together to produce a better society.
