A true-breeding plant with yellow seeds is bred with a true-breeding plant with green seeds. What color seeds will the offspring produce where yellow is the dominant seed color?A.
all yellow

B.
all green

C.
three-fourths yellow and one-fourth green

D.
three-fourths green and one-fourth yellow

Answers

Answer 1
Answer:

Answer:

The correct answer would be A. all yellow.

Let "Y" be the dominant allele and "y" be the recessive allele of the gene responsible for the color of the seeds.

Dominant allele "Y" codes for the yellow color of the seeds when present in homozygous as well as heterozygous condition whereas recessive allele "y" codes for the green color of the seeds only when present in homozygous condition.

Now, the genotype of a true-breeding plant with yellow seeds would be YY and that of a true-breeding plant with green seeds would be yy.

The gametes formed by yellow seed plant would be Y and gametes formed by green seed plant would be y.

The cross will result in the production of offspring each with genotype Yy.

Hence, all the offspring plants would produce yellow seeds as yellow is a dominant character.
Answer 2
Answer: A. all yellow

they will look all yellow but all will be heterozygous

Step 3: State your hypothesis

The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables. The hypothesis should relate back to your original question and must be testable.
1. What are some special structures within a cell?

Answer:
different types of cells have different structures but I’m going to assume this is on animal cells. The cell has tons of special structures, but some simpler ones are; nucleus, cell membrane, ribosome, cytoplasm, mitochondrion. I’ll attach a diagram!

2. What is step three in the scientific process

Answer:
The scientific process is as follows
1. Observation
2. Question
**3. Hypothesis**
4. Experiment
5. Conclusion
6. Result

3. Do cells make up all living things? (Use CER for this question)

Answer:
Yes they do!

From my understanding CER is cite, explain reasoning. I don’t know if your teacher provided you with material to cite but you should probably use your class textbook or any other recent class reading. Here’s a graphic organizer for your written answer

Cite: [quote from the text with page number]

Explain: explain why cells make up all living things, using the quote as evidence.

Reasoning: explain how the text connects to your claim.

Sexual reproduction requires cells to undergo ______, whereas only _______ is necessary for asexual reproduction.A.
fertilization; meiosis

B.
mitosis; meiosis

C.
mitosis; fertilization

D.
meiosis; mitosis

Answers

Sexual reproduction requires cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction. Thus, the correct option is D.

What is Sexual reproduction?

Sexual reproduction involves the production of new organisms through the combination of genetic information of two individuals which are of different sexes. In most of the species, the genetic information is being carried on by the chromosomes in the nucleus of reproductive cells which are known as germ cells or gametes, which then undergo fertilization and fuse to form a diploid zygote.

Gametes are produced through meiosis because these are haploid. Thus, sexual reproduction required cells to undergo meiosis, whereas only mitosis is necessary for asexual reproduction.

Therefore, the correct option is D.

D. Meiosis because babies or humans are made of a combination of our parent’s genes. Meiosis is mitosis times 2. So you get more pairs that are different. Mitosis produces identical offsprings.
