Bees can pollinate all types of flowers.
Answer:
Yes,it's clear that bees play a vital role in food production. They are excellent pollinators! Most food crops—including fruits, vegetables, nuts, and seeds—must go through pollination. That's the process of moving tiny pollen cells between plants to help them make seeds.

What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.

Earth is special because it is an ocean planet. Water covers 70 percent of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.There are multiple reasons for earth to be a special planet. Reasons are as follows
1.Earth is the only planet known where intelligent life exist.
2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.
3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.
4. Earth has Van Allen radiation belts which protects it from cosmic rays.
5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.
6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.
7. Tectonic plates of earth differentiates it from most other planets.
8. Earth has a solid crust unlike the gaseous planets.
9. Earth has been gifted with a medium sized star which release solar winds and protect us from the harmful radiation of outer space.

why do some scientists think the "origins" question cannot be answered scientifically?
I personally think because of the intelligent design vs. evolution theories. what do you think?
Answer:
agreed
Explanation:
for certain things like how humans were created and everything like that I totally agree because you can't really do research if something that over the years is probably either hidden or gone so if there wasn't any evidence of how any of this came to be by now it would be gone. some things you just can't put a logical explanation on
The table below shows part of the process of DNA replication:
Original DNA Strand
Complementary DNA Strand
A-C-C-G-T-A-C
T-G-G-A-A-T-G
What is the most likely effect this could have on genetic information going forward?
оооо
There will be no change in the genetic information that gets transmitted because the complementary strand will never be used as a template
O There will not be a change in the genetic information that gets transmitted because the cells having the new section of DNA will correct any mutations
There will be a change in the genetic information that gets transmitted due to the complementary strand being used as a template in future DNA replication
There will be a change in the genetic information that gets transmitted because the sections of DNA with mistakes will be passed on to make future generations stronger.
Answer:
There will be a change in the genetic information that gets transmitted due to the mutation in the complementary strand being used as template in future DNA replication.

Please help, 100 points! Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?
A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years. (This one is obviously wrong)
Around 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.
What is the origin of life?Even before the 3.5 billion years ago when the oldest fossils on Earth were discovered, just at the conclusion of the time of late intense bombardment, there is evidence of biological activity.
The 3.5 billion-year-old "stromatolites," which are hard structures created by bacteria, also provide evidence of their presence. Stromatolites are produced when microbe-made sticky mats catch and organize sediments into layers.
It has been discovered that trophozoites contain organic material from 3.5 billion years ago. 3.5 billion-year-old rocks have been found to contain microbial remnants, some of the planet's earliest evidence of life.
Therefore, 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

[URGENT!!] David feeds his cattle with root vegetables such as turnips. Which type of feed includes root vegetables such as turnips?
A. concentrates
B. dry roughage
C. green roughage
D. silage
E. dry matter
Answer:
D.
Explanation:
Answer:
Green Roughhage
Explanation:
Roughages are high in fiber and low in digestible nutrients. There are three kinds of roughages: dry, green, and silage. Dry roughage such as hay has a low moisture content. Grasses in pastures and root vegetables (like turnips) are called green roughage and have a high moisture content. The fermentation of green plants results in the formation of silage.

PLEASE I NEED HELP ASAP!! WILL GIVE BRAINLIEST AND 100 POINTS!!! When you cross two heterozygous organisms, what is the probability that the offspring will show the dominant phenotype? (HINT: You may want to draw a Punnett Square on a separate piece of paper to help.)
A. 100
B. 75
C. 50
D. 25
E. 0
Answer
75% chance
Explanation:
The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.
The correct answer is:
Option B. 75%
The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.
The dominant alleles are always expressed in purebred and heterozygous conditions.
The recessive alleles are expressed in purebred conditions only.
In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.
Thus, the chance of progeny will have round-shaped seeds is 75%.

If 30% of a DNA sample is composed of thymine nucleotides, what percentage of the DNA sample would be composed of cytosine nucleotides?
Answer:
20%
Explanation:
Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.
DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,
Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.
While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.

Is it varration , overpopulation or adaption On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own.
Answer: this is adaptation, but not in the way suggested in the question.
Explanation:
The question is suggesting that the 1% or so of turtle hatchlings that make it to maturity are the result of a variation that gives a selective advantage. This is not so. The only thing being selected for is sheer luck. The underlying adaptation is that all eggs hatch within a short period, so that predators are overwhelmed by numbers and some offspring by chance make it to the water, still dangerous, but less so than the sand. After the hatchlings reach the sea chance will still be a factor, but it is at this stage that natural selection may operate on advantageous variations.
There are two reproductive strategies, common to plants as well as animals. Turtles represent one of those strategies, which is to invest resources to produce large numbers of immediately self-sufficient offspring so that at least some will survive. The other strategy is to produce one or few offspring and invest resources in protecting and feeding it or them until self-sufficient and capable of surviving to maturity.
These are adaptations which are selected for because they confer advantage for the species concerned. One or the other may be the better solution depending on the species. Mammals, for example, invest in the latter strategy.
