Answer:
False
Explanation:
Crossing over is a phenomenon unique only to the process of meiosis. It is the process whereby a segment of genetic material is exchanged between the non-sister chromatids of homologous chromosome (similar but non-identical chromosomes from both parent).
Crossing over occurs when homologous pairs lie side by side to form a structure called TETRAD in the PROPHASE I stage of meiosis. Hence, according to this question, it is FALSE as crossing over does not occur in the metaphase stage.

Describe the sun’s role in the sustainability of the Earth’s environment.
Without the sun, most/all life would cease to exist, especially once depending on light energy from the sun like plants, forming the bases of life.
Explanation:
Plant (producers) use light energy to photosynthesis, producing the energy or food other herbivores (plus, our primary&secondary consumers) dependant upon, to survive; then, they get preyed upon (by our tertiary consumers) - structuring the food chain as we all know of. Hence, sustaining life/ living organisms on earth, for generations to come.
Thus, all life on earth as we know it, basically, won't exist. Abiotic factors are the one's to live a happy ever after. There are non-living, once that don't undergo cellular respiration like us humans, e.g., rocks don't respire.
Anyways the sun is a star, one day (millions to billions years onwards) it's predicted to engulf our earth, when transitioning to become a red giant. So, it might not sustain earth forever.
Don't panic, you won't live to experience this! How fantastic does this sounds?
Hope this helps!
how does photosynthesis transforms light energy into stored chemical energy
Answer:
The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.
Explanation:
The process of photosynthesis transforms light energy into stored chemical energy with the help of green-colored pigment in the chloroplast which captures this light radiation and allows it to transform into chemical energy.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2_ + 12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]After capturing the light radiation from the sun, chlorophyll in the chloroplast significantly converts carbon dioxide plus water into sugars plus released oxygen. This sugar can be further utilized as a source mechanism to derive energy for metabolic activities.
Therefore, the process of photosynthesis efficiently transforms light energy into stored chemical energy.

noun concentration means the process of People directing effort and attention in a particular thing.
Explanation:
forexample
he stressed the need for greater concentration on environment issues.
The word concentration denotes the act of gathering or collecting something. It is formed from the verb concentrate and the suffix- ion.
Thus, it denotes the action of concentrating a material, energy, or attention in a particular area or at a greater level. Concentration may be used to describe a variety of things, including the density of a material, the amount of focus or attention paid to an activity or issue.
The percentage of a certain ingredient in a combination, or the gathering of resources or people in a certain region. In general, concentration refers to the process of amplifying, concentrating, or collecting materials or forces in a certain situation.

Look at the diagram. Seed 1 dispersed by the ______. Which one word completes the sentence
Seed 1 dispersed by the wind and water.
Why are seeds dispersed?Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
Wind, water, gravity, ballistic (where the seeds are ejected by forceful and often explosive mechanisms) and animals are the main ways seeds are dispersed.
Drop and roll – the casing of the fruits from trees, such as horse chestnut, split when they land on the ground. On impact the fruit then rolls away from the tree.

Their sons have a 25% chance of having hemophilia
There is a 50% chance that their daughters will have hemophilia
None of the daughters from the union will have hemophilia.
