What is crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.
The same genes may be present on the two chromosomes in different versions. The genetic material in the germ line can switch places, a process is known as crossing over.
Pairs of chromosomes from each parent align to allow similar DNA sequences from the paired chromosomes to cross over one another during the development of egg and sperm cells, commonly known as meiosis.
Therefore, the percentage that will be speckled is 20%.

6. Which of the following statements about niches is false?
A.Many different types of organisms can occupy the same niche.
B.The hermit crab uses a leftover mollusk shell as a home. His shell is part of his niche.
C.The crow is a quite adaptable organism and has a broad niche.
D.One aspect of a sloth's niche is the type of food it eats.
Answer:
a i think
Explanation:
The following statements about niches are false: The crow is a quite adaptable organism and has a broad niche, which is option C, as the niche is not a broad place but a place where the individual spends most of the time living and reproducing.
What exactly are "niches"?A niche is the place that an organism plays in its environment, including the physical space it occupies and the resources it uses, and it is the way that an organism interacts with its environment and with other organisms, whereas niches can be occupied by many different types of organisms, and in some cases, different organisms may even occupy the same niche at the same time, which is known as niche overlap.
Hence, the following statements about niches are false: Option C is the crow, which is a highly adaptable organism with a wide niche.

If a cell in G1 phase has 4 chromosomes, how many chromosomes will it have by the end of meiosis?
Answer:
G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes are duplicated by the cell. III.
Explanation:
This molecule provides stability to the phospholipid bilayer and without it the membrane would easily fall apart.
Answer:
The correct answer is - cholesterol molecules.
Explanation:
Cholesterol molecules are the molecules that acts as a bidirectional regulator for the lipid bilayer as it provides fluidity by raising the melting point of the membrane at high temperature and stabilize the membrane.
On the other hand, it also prevents the membrane from clustering or being tough or stiff by intercalates between the phospholipids at low temperatures. Therefore it is the molecule that provides stability to the membrane.
A human cell that has 46 chromosomes would have __ daughter cells that each have __ chromosomes after mitosis.
Answer:
2 daughter cells, 46 chromosomes
Explanation:
Mitosis is reproduction of somatic cells, or body cells. It's end product will always be 2 daughter cells, each identical to one another, therefore meaning, it will also have the same number of chromosomes!
Answer: one daughter cells and each have 23
Explanation: mitosis is the first then meiosis
People who have leukemia, a cancer that affects white blood cells, are often given Cytarabine. This drug inhibits the synthesis of DNA. Which phase of the cell cycle is most affected by Cytarabine?
A
Interphase
B
Cytokinesis
C
Prophase
D
Anaphase
Answer:
I think interphase because fna synthesis happens within the s-phase of the cell cylce and 5he s phase is suring interphase and not mitosis
The phase of the cell cycle which is most affected by Cytarabine is the Interphase. Thus, the correct option is A.
What is the cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The entire cell cycle can be divided into two phases.
The InterphaseThe M-phase (division phase).As per the question, the drug Cytarabine inhibits the synthesis of DNA, it definitely inhibits the interphase of the cell cycle. This is because the synthesis of DNA occurs in the S-phase of the cell cycle which is a substage of the interphase.
Therefore, the interphase of the cell cycle must be affected by the drug Cytarabine. Thus, the correct option for this question is A.

A) Karen: I think they must all be different species of ladybugs.
B)Troy: I think each ladybug has the same number of spots as its parents.
C)Isaac: I think it depends on the age of the ladybugs. As they get older they add more spots.
D)Fred: I think it has to do with the sex of the ladybug. Males will add more spots to compete for the females.
E) Andrea: I think it depends on what each ladybug was born with.
F) Alice: I think they change their number of spots when there is a need for them to do so.

In the oldest fossils found in Bitter Springs (Cyanobacteria), why can we only find the remains of single celled organisms
Answer:
Due to presence at early days of the planet.
Explanation:
We only find the remains of single celled organisms in the oldest fossils because the single celled organisms are the organisms that were present in the early days of this planet. These single celled microbes were present about 3.7 billion years ago while on the other hand, the oldest rocks are only a little older i. e. 3.8 billion years so these single celled organisms are considered as oldest fossils on this planet.

How does the attachment of spindle fibers differ between mitosis and meiosis I?
In mitosis, the spindle fibers from two poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
WHAT IS MITOSIS AND MEIOSIS?
Mitosis and meiosis are two kinds of cell divisions. Mitosis involves separation of a single parent cell to produce two genetically identical cells while meiosis involves the separation of a single parent cell to produce four genetically different daughter cells.WHAT IS SPINDLE FIBER?
Spindle fibers are structures that emanate from centrosome organelles and responsible for the separation of chromosomes during karyokinesis (nuclear division). During the two cellular divisions (mitosis and meiosis), spindle fibers attach to the centromeres of each chromosome in order to align and eventually divide them.However, in mitosis, spindle fibers from two opposite poles attach to each chromosome but in meiosis I, the spindle fibers from only ONE pole attaches to the chromosome.
