What % of energy does plants receive from the sun
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.
Explanation:
Which two parts of sedimentary rocks formation include the breakdown and carrying away of existing rock
Answer:
weathering
erosion
Explanation:
Weathering can be explained as the
breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of
weathering and erosion could be water, salt, animal as well as plants.
It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.
Answer:
weathering

which subatomic particle of an atom moves around the nucleus
Answer:
Electrons
Explanation:
electrons, move around the nucleus
and electrons have a negative electrical charge.
Answer:
Electrons
Explanation:
The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge.
Being genetically identical to the parent is most advantageous for organisms in which situation?
A.
Many offspring are needed in a very short amount of time.
B.
The environment is just like the one the parent lived in successfully.
C.
Mates cannot be found easily and the species is dying out.
D
The environment is changing and fast reproduction is needed.
Answer:
B
Explanation:
In asexual reproduction organisms give rise to genetically identical clones and reproduce in higher amounts, hence option d environment is changing and the need for fast reproduction is correct.
What is genetically identical?The children are clones of both the parent and each other. Asexual reproduction has several advantages, including the ability to fast increase the population when conditions are favorable.
There is just one parent required. During sexual reproduction, two people's genetic material is united to generate genetically diverse children who differ from their parents.
It is assumed that the genetic variety of sexually generated offspring gives species a higher chance of survival in an uncertain or changing environment.
Therefore fast reproduction is needed, because the environment is changing, and asexual reproduction makes a higher population, hence option d is correct.

What is an astronomical unit or AU?
A)
A unit of time equal to one light year or 6 trillion miles.
B)
A unit of distance equal to the average distance from Earth to the Suntor
93 million miles.
A unit of distance equal to the size of the Milky Way Galaxy or 100,000
light years across
D)
A unit of time that is equal to the amount of time it takes light to travel
from the Sun to Earth,
Answer:
B
Explanation:
The correct option should be B.
The Astronomical Unit, AU, is a measurement unit for length in general astronomy and represents the mean or the average distance of the sun from the earth.
Mathematically, in astronomy,
1 astronomical unit = 150,000,000 km
But then, 1 km = 0.621371 mile
Hence,
150,000,000 km = 150,000,000 x 0.621371 miles
≈93,000,000 miles
Therefore, 1 astronomical unit can also said to be approximately equal to 93,000,000 miles.
The correct option is B

A black hybrid rabbit is crossed with a white purebred rabbit.
What is the probability of an offspring being black?
A. 25%
B. 50%
C. 75%
Answer
A. 25%
Explanation:
This is because the black hybrid would be 50% one breed and 50% another breed. Then the white purebred is 100% one specific breed. So by mating, all of those breeds that the parents have all reduce by 1/2 for the offspring.
If I have 8 DNA nucleotides, how many
DNA
bases do I have?
How many base pairs?
Answer:
Each nucleotide contains phosphate, sugar (of the deoxyribose type), and one of the four bases (Figure 8-4). When the phosphate group is not present, the base and the deoxyribose form a nucleoside rather than a nucleotide. The four bases are adenine, guanine, cytosine, and thymine.

What is an observation? What do you use to make an observation?
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!

1. Fallopian tube
2. Uterus cavity
3. Bladder
4. Urethra
5. Ovary
6. Ovary
7. Uterus
8. Vagina
Explanation:
The vagina is a muscular tube-shaped connection that extends from the vaginal opening to the uterus. Vagina walls are very muscular, which allows contraction and expansion movements. It is located just between the urethra/bladder and the rectus. Menstruation, copulation, and birth occur through the vagina.
The uterus is a muscular and hollow organ, also located between the bladder and the rectus. The uterus wall is formed of three layers: perimetrium, mesometrium, and endometrium. This organ is separated into two parts: the uterus body and the cervix, which protrudes to the superior area of the vagina. Here is located the uterine opening that communicates the vagina with the uterus cavity. The final rounded portion is called "uterus fundus", and each of the two extremes is called "uterus horn". These horns are united to the Fallopian tubes.
Fallopian tubes are ducts that communicate each of the ovaries with each of the uterus horns. These tubes receive the oocytes that are getting out of the ovaries and carry them to the uterus. In their way, they might meet a spermatozoid and be fertilized.
Both ovaries have an oval shape, of approximately 3 cm in length each and 1 cm in width. They are located at each side of the uterus and are in charge of the production of the feminine gametes (the whole ovulation process).

But you may be surprised to learn that the family of vertebrates to which modern birds are most closely related is the crocodiles , which evolved, like dinosaurs, from a population of archosaur reptiles during the late Triassic period.

why is it beneficial for female peacocks to choose to mate with a male peacock with a full colorful trains?
URGENT
Answer:
Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.In eukaryotic cells, DNA is packaged with proteins into structures called
