Which of the following best describes the cytoplasm in the cell?
a watery substance where cell processes take place
a hard substance that digests food molecules
a watery substance that keeps molecules from leaving the cell
a hard substance that keeps the cell rigid
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
It is a jelly-like liquid that surrounds everything inside the cell.
A pear plant with the genotype Aa can produce gametes containing:
1: either AA, Aa, or aa
2: only the dominant A
3: either A or Aa
4: only the recessive a
5: either A or a
The genotype of pea plant.
A plant of pear with a genotype that is Aa and makes a gamete having dominant and recessive traits. The all possible combinations such as AA, aa etc. can be produced.
Hence the answer is either A or a.
As per the Punnett table, the Aa will firm the gametes that are aa, AA, or Aa.Depending on the dominance of the trait or gene. The planet is found with larger gametes will have A and fewer gametes will have a. Thus the option E is correct.Learn more about the pear plant.

Explanation:
Original DNA strand: ATT GAG CC Mutated DNA strand: ATT GAG CT What type of mutation does the example above demonstrate?
Original DNA strand: ATT TGA GCC
Mutated DNA strand: ATT TGA GAC C
What type of mutation does the example abo w demonstrate?
The examples above demonstrate a substitution mutation.
A substitution mutation is a type of mutation that occurs when one nucleotide in the DNA sequence is replaced by another nucleotide. In the first example, the original DNA strand has the sequence "ATT GAG CC," but in the mutated DNA strand, the nucleotide "C" is replaced with "T" at the third position, resulting in "ATT GAG CT." This single nucleotide substitution is a specific type of substitution mutation known as a missense mutation.
In the second example, the original DNA strand has the sequence "ATT TGA GCC," but in the mutated DNA strand, the nucleotide "C" is replaced with "A" at the sixth position, resulting in "ATT TGA GAC C." Again, this is a substitution mutation where a single nucleotide is replaced by another.
Substitution mutations can have different effects on the resulting protein. In some cases, the change in the DNA sequence may lead to the production of a different amino acid during translation, which can alter the structure and function of the protein. Depending on the specific location and nature of the substitution, it can have varying impacts on the phenotype and may or may not result in a noticeable change in the organism.

please helpme on time limit and explain
Answer:
Net force is 100 N
Explanation:
You will use the formula to find the net force/force.
mass = 0.05 kg
acceleration = 2000 m/s^2
F = m × a
F = 0.05 kg × 2000 m/s^2
F = 100 N (Newtons)

When is the most possible time for fertilization if the menstrual cycle is 28 days? Why?
Answer:
You're most fertile about 12 to 14 days before your next period starts. This is the time of the month when you're most likely to get pregnant. It's unlikely that you'll get pregnant just after your period, although it can happen.
Explanation:
This is because at this stage you are ovulating (an egg is being released from your ovaries)

then you plant and grow the seeds. Many of the self-fertilized plants have some colored and
some white flower offspring. You choose one of the plants from a family of all colored flower
plants, let it self-fertilize, then you plant and grow its seeds. All the plants you get have colored
flowers. Now what?
A. This colored flower
plant is pure-bred.
B. This isn't a pure-bred plant, you
need to start all over again.

rabbits and gorillas have fur
Explanation:
Answer:
A cladogram is the diagrammatic result of an analysis, which groups taxa on the basis of synapomorphies alone. There are many other phylogenetic algorithms that treat data somewhat differently, and result in phylogenetic trees that look like cladograms but are not cladograms.

Write a research paper about do you believe in evolution? Why or why not?
Answer: Yes
Explanation: Evolution is a fact, but not all evolve at the same time, not all have the equality of the study and for this reason evolution is delayed worldwide.
Answer:
Yes, I belive in evolution because of how muech the world has changed it's form over they years. To break it down a little more take humans for an example we weren't always like this we didn't have all these citys, buildings, tec, and so on. Back in the days when we still have native tribes and explorers they didn't have a house to sleep in they slept in tents or in carrages but as time evolved so did our minds and our brains thats when cabins started then after that houses then cars, power, and even more, but they had to learn how to do this. They evolved their minds to create they evolved to make it throught bad times they had to evolve along with mother nature her self. we all made it this far thanks to the great mind of evolution adn thats why I believe.

What are two things that taxonomy give scientists?
Answer:
Taxonomy entails the description, naming, and classification of living things. Well, it helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.
Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related.
