The daughter cells have n chromosomes. The mother cell has 2n.
The daughter cells have the same type of chromosomes, but a different number
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Answers
Answer:
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Explanation:
Daughter cells are identical means same shape and structure to the parent cells because the parent cell is divided equally and as a result daughter cells are produced. In mitosis cell division, two daughter cells are produced having double number of chromosomes just like parent cell, whereas in meiosis cell division, four daughter cells are produced having half number of chromosomes.
What’s the correct mRNA sequence from the DNA strand: TAC GCC CGA ATC
A. ATG CCG GCU TAG
B. AUG GCC GCU UAG
C. AUG CGG GCU UAG
D. AUG CCG GCT UAG
E. ATG CCG CGT TAG
Answers
Answer:
C. AUG CGG GCU UAG
Explanation:
This works the same as a normal DNA strand, A=T, C=G, except for one difference. Thymine is not an mRNA base, instead it is Uracil. Therefore, if there is an A, you would typically replace it with a T, but for mRNA you will replace it with a U. Keep in mind you will still replace the T in the DNA strand with an A in the mRNA strand :)
In Drosophila, the dominant allele Cy (Curly) results in curly wings. The cross Cy/ x Cy/ (where represents the wildtype allele of Cy) results in a ratio of 2 curly : 1 wildtype F1 progeny. The cross between the curly F1 progeny also gives a ratio of 2 curly : 1 wildtype F2 progeny. How can this result best be explained
Answers
Answer:
d
Explanation:
Using a Punnet square to represent the given information
The cross between Cy + and Cy + can be computed as:
Cy +
Cy Cy Cy Cy +
+ Cy + ++
From what we see above, it is above that the ratio of Curly to wildtype is in the ratio of 2:1
This illustrates that the genotype Cy Cy is lethal. This is explained when two curly F1 are crossed which resulted in the same ratio.
Hence, the inheritance of Cy/Cy is fatal.

Answers
Answer:
A,C,D
Explanation:
Produce spores, Contain hyphae, Contain a fruiting body
Fungi produces spores containing hyphae and a fruiting body. So, the correct options are A, C and D.
What is Fungi?A fungus is defined as a member of a group of eukaryotic organisms which includes microorganisms such as yeast and mold, as well as the more familiar mushrooms.
Fungi are described as eukaryotic, non-vascular, non-motile and heterotrophic organisms which can be unicellular or filamentous. They reproduce by means of spores which exhibit the phenomenon of alternation of generations. Fungi lack chlorophyll and therefore cannot photosynthesize.
Fungi are classified in four divisions such as the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi).
Thus, Fungi produces spores containing hyphae and a fruiting body. So, the correct options are A, C and D.

Approximately 75% of the Earth's surface is covered in water. Why is water considered such a precious resource?
Answers
Answer:
Water is precious since it is one of the most basic commodities that sustain the life of human beings, animals and plant. Without water, it would be impossible for any form of life to exist in the universe. Close to 75% of the Earth is covered with salt water, while 2% of the surface contains frozen water.
Explanation:
Why is water a precious resource?
It is needed for all living things and must be managed well to ensure we have enough for our needs and to protect our environment. Water is a precious resource. We can't live without it. Clouds formed by this vapor ensure that water falls back down to Earth as rain, sleet, snow or hail.Water resources are sources of water that are useful or potentially useful to humans.

D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?
Answers
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
What is independent assortment?Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.
This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.

Answers
hope it helps!!
Sorry if it’s wrong
The type of heredity is shown in the pedigree is autosomal recessive. Hence option D is correct.
What is heredity?Heredity is defined as the whole of biological mechanisms via which certain traits are passed down from one generation to the next. The system by which traits, similarities, and differences are passed down from one generation to the next is called heredity. A guiding biological principle, heredity explains why children resemble but differ from their parents.
Autosomal recessive is defined as when one variant is found on both alleles of a particular gene, a genetic condition is present. The disease must be autosomal recessive if any affected founding daughter has two unaffected parents. Both parents must possess the recessive gene in order for the affected person to inherit it from them.
Thus, the type of heredity is shown in the pedigree is autosomal recessive. Hence option D is correct.

What is the difference between an instinct and a learned behavior?
Answers
Answer:
See below.
Explanation:
The major difference between an instinct and a learned behavior is how it was picked up. An instinct is something that you're born knowing (think of being programmed to do certain actions or display specific behaviors.) An example of this would be how homing pigeons are "wired" and remember their home when they migrate. A learned behavior, on the other hand, is something you have to learn as you don't have a certain behavior, skill, etc. This can be a language, how to walk/talk, personality, likes and dislikes, learning how to read, write, or learn information. So right now, learning about this is displaying a learned behavior (being able to process information and read). :)
Why would water move faster through one kind of tree compared to another, and what might that tell us about their life cycle and susceptibility to environmental changes?

Explanation: if it is really cold a mouse with thicker fur (phenotype) will do better
Environmental conditions often favor one selection over another.
In the context of evolution, selection refers to the process by which certain traits or characteristics become more or less common in a population over time. This process occurs due to environmental conditions that favor certain individuals with advantageous traits, leading to their increased survival and reproduction.
For example, consider a population of birds living in a forest with two distinct color morphs: light and dark. If the forest becomes darker due to increased tree cover, the dark-colored birds might be better camouflaged and have a higher chance of surviving and reproducing. Over time, the proportion of dark-colored birds in the population would increase, as they have a selective advantage in the new environmental conditions.
Similarly, if the forest becomes lighter, the light-colored birds may become more successful in avoiding predation and finding mates. In this case, the environmental conditions would favor the light-colored birds, leading to an increase in their frequency within the population.
Therefore, the term "selection" refers to the process by which environmental conditions favor certain individuals or traits, resulting in changes in the frequency of those traits within a population over time.
