Answer:
The correct answer is - All offsprings are black-furred mice.
Explanation:
In this case, the parent mice are black and a cross between these mice produces offspring one allele from both parents. Here, black fur is dominant over white fur.
All the babies are with dark fur colors, no whites as black is a dominant color, so it produces black due to cross between two true breeds.

A child is born with hemophilia (inherited as an X-linked recessive) and Klinefelter's syndrome to parents who both have normal blood clotting. In which parent (mother or father) and during which round of meiosis (I or II) did the nondisjunction event occur
Answers
Answer:
mother
Explanation:
Hemophilia is a sex-linked recessive disorder caused by a mutation in one of the genes responsible for encoding the clotting factor proteins (factor VIII or factor IX), which are located on the X chromosome. Moreover, the Klinefelter syndrome is caused by men having an additional X chromosome. In this case, the nondisjunction occurred from the mother because her gamete included an extra X, it is for that reason that all genes localized on the X chromosome, including the defective gene involved in hemophilia, can cause all of her sons to be affected by the disease in some generation. Thus, sister chromatids did not separate during meiosis (Anaphase II) and caused two copies of the defective allele for the hemophilia trait.

Answers
Answer:
The correct answer is - Nematocycst.
Explanation:
Nematocysts are aquatic animals that contain stinging cells known as cnidocytes. These organisms are members of the phylum Cnidaria. These carry a organelle called cnida or cnidocyst.
An example of such an organism is Jellyfish. Sting cells are specialized neural cells that release extensive Golgi secretion venom that causes a stinging experience to the prey the nematocyst.

C. Atmospheric carbon dioxide may dissolve in ocean water.
D. The burning of fossil fuels adds carbon dioxide to the atmosphere.
E. Activities that produce or take up carbon dioxide vary with the seasons.
Answers
Answer:
the answer is A and D
Explanation:
because yes
Cellular respiration and photosynthesis are significant carbon cycle processes. The processes via which carbon is recycled in the biosphere are known as the carbon cycle. Thus, option A, D is correct.
What is the effect of carbon dioxide to the atmosphere?
Unlike cellular respiration, which releases carbon dioxide into the environment, photosynthesis eliminates carbon dioxide from the atmosphere.
When fossil fuels are burned, a greenhouse gas called carbon dioxide is massively released into the atmosphere. Greenhouse gases, which trap heat in our atmosphere, are to blame for global warming.
Therefore, Photosynthesis and cellular respiration have opposite effects on carbon dioxide levels and the burning of fossil fuels adds carbon dioxide to the atmosphere.

The authors describe an important experiment in which scientists showed strong support for the hypothesis that bdelloid rotifers have reproduced asexually for millions of years. Briefly describe the results from their experiment that supported this conclusion
Answers
Answer:
Bdelloid rotifers are small metazoans, a class of very small invertebrates that can visible through a microscope only. They reproduce asexually and found in temporary or permanent freshwater.
Bdelloid rotifers population shows only females in this population and Males not found yet, which suggests that females asexually produce identical progeny. The process called parthenogenesis. The organisms that sexually produced their DNA has two copies of the genome that may or may not be identical but in case of asexual reproduction, there are always identical copies produce.

how do allosteric enzymes activate and inhibit chemical reactions in a living organism?
Answers
Answer:
Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.
