matution:a change in the chromosomes or genes of a cellExplanation:
crossing over(or recombination) between chromotids or homologous chromosomes during meiosis
Mutation and Genetic recombination are two possible sources of this genetic variation.
What is Genetic Variation?Genetic variation is defined as the difference in DNA between individuals or between populations where multiple sources of genetic variation include mutation and genetic recombination. Mutations are the ultimate source of genetic variation, but other mechanisms, such as genetic drift, contribute as well.
There are two main sources of Genetic variation which are as follows:
1. Mutation:
Mutation describes genetic variation caused by changes in the genes of individuals living in a population.
2.Genetic recombination:
Genetic recombination has been described as the fusion of gametes promoting different combinations of genes in a population leading to genetic variation.
Thus, Mutation and Genetic recombination are two possible sources of this genetic variation.

What kind of molecules were formed by abiotic synthesis? How did they form?
Answer: Abiotic processes synthesized small organic molecules, such as amino acids and nucleotides. These monomers were joined into polymers, including proteins and nucleic acids. Polymers were packaged into “protobionts,” droplets with membranes that maintained an internal chemistry distinct from their surroundings.

How is photosynthesis and cellular similar, and how are they different?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.

!!!!!?HELP WILL MARK BRAINLIST ANSWER AND MORE POINTS!!!!!!
Answer:
The forecast for Eastern Texas will be Rain
Explanation:
The reason why i believe it will be rain is because in the map it shows more green than blue pink or purple, green is for rain ,blue is for snow, pink is for mix, and lastly purple is ice, As you can see in the map it shows a lot of green also the front type weather conditions look like waves so it most likely means it is rainy and windy.

Brainliest involved :) help
Answer:
B
Explanation:
A haploid has one, which refers to the sex cells (eggs/sperm)
diploid has 2
We have 2 genes here, so we are coding for 2
different traits, AKA 2 distinct and separate
phenotypes
However, both phenotypes are present in each
offspring cat.
So, for example we could have a hairy, sink-
loving cat (like one of the parents) or a
hairless, sink-hating cat (like the other
parent). What are the other possibilities for
phenotype?
Make sure to include both traits (hair/hairless
and feelings about sinks) for each possible
phenotype.
Answer:
50% hairy and love sinks
50% hairless and hate sinks
Your teacher asked you to explain the photosynthesis model to a new student. Examine the model and determine what you should include in your explanation.
Choose ALL that apply
A) Plants get water from the soil from their roots.
B) Plants require sunlight, water, and carbon dioxide to make sugars.
C) Plants absorb water, oxygen, and carbon dioxide through their leaves
D) Plants bring'in carbon dioxide and release oxygen through their leaves Plants bring in oxygen and release carbon dioxide through the stomata in then leaves
Answer:
a, b, and d are the correct answers
Explanation:
Photosynthesis is the process in which plants produce their food as well as food for other organisms. Thus, options A, B and D are correct.
What is photosynthesis?Photosynthesis involves the conversion of light energy into chemical energy by plants.
Plants carry out photosynthesis in the presence of sunlight. They take up water and carbon dioxide to produce glucose and release molecular oxygen in the atmosphere.
This glucose is a six carbon sugar which can then be utilized to produce other carbon rich macromolecules.
Photosynthesis take place in the chloroplasts of the plant leaves.
Plant leaves contain green coloured chlorophyll pigment which traps the solar energy.
Only the green plants and some special bacteria carry out photosynthesis as chlorophyll is the reaction centre for photosynthesis.
Temperature, Light, moisture and carbon dioxide concentration are some of the factors that affect the rate of photosynthesis.
Therefore, photosynthesis is a prime event through which animals obtain their food and oxygen.

b. How does weathering affect Earth's surface?
Answer:
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
Explanation:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

How do clouds scatter light energy ?
Answer:
Non-selective scatter is primarily caused by water droplets in the atmosphere. ... In the visible wavelengths light is scattered evenly, hence fog and clouds appear white. Since clouds scatter all wavelengths of light, this means that clouds block most energy from reaching the Earth's surface.
