5. When a hawk eats a mouse and then uses the energy from the mouse to fly,
the hawk's body converts — *
A. mechanical energy to chemical energy
B. thermal energy to mechanical energy
C. chemical energy to mechanical energy
D. mechanical energy to thermal energy

Answers

Answer:

Chemical To Mechanical

Explanation:

The Chemical energy fueled the hawk and the hawk used that energy to fly, basically like a car needs gasoline to move

The hawk body should be converted to the chemical energy to mechanical energy.

Conversion of energy:

Since the hawk ate the mouse and after this it used the energy from the mouse to fly. Since food should be treated as the chemical source while the hawk flying should be treated as the mechanical source. Also, the chemical energy should fuel the hawk and the hawk should used the energy to fly where the car required gasoline for movement.

Therefore, option c is correct.

Which image represents cytokinesis in a plant cell?​

Answers

Answer:

D

Explanation:

gl (:

A crucial function of cytokinesis is to divide the cell in half and make sure that one nucleus is placed in each daughter cell. Thus, option D is correct.

What is the importance of cytokinesis in plant cells?

The four steps of cytokinesis are membrane insertion, contraction, and completion. Animal and plant cells experience these stages in different ways.

The assembly and action of an actomyosin-based contractile ring during animal cytokinesis were characterized as occurring at the cell periphery.

In contrast, it was thought that plant cell cytokinesis involved the centrifugal formation of a new cell wall through the fusion of vesicles generated from the Golgi apparatus.

Therefore, The process of cytokinesis begins at the anaphase phase of nuclear division and lasts until telophase.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?

Answers

Answer:

ACDB (or BDCA)

Explanation:

The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

In a pedigree, a rare trait appears in both sexes with equal frequency, and each affected offspring has one affected parent. What is the most likely mode of inheritance?

Answers

Answer:

Autosomal dominant inheritance

Explanation:

The most likely mode of inheritance of the trait would be autosomal dominance.

In autosomal dominant inheritance, a dominant allele on a non-sex chromosome is responsible for its transmission across generations. Unlike autosomal recessive traits that require two recessive alleles for their transmission, only one dominant allele is required for autosomal dominant traits and the implication is that it appears in every generation and both males and females have an equal chance of inheriting such traits.

Hence, for a rare trait that appears in both sexes with the same frequency and each affected offspring has one affected parent, the most likely mode of inheritance would be autosomal dominance.

Which family in the periodic table has metals that are usually harder than other metals?

Alkali metals
Alkaline earth metals
Lanthanide series
Transition metals

Answers

Answer:

Transition metals

Explanation:

The transition metals are usually harder than other metals such as the alkali metal, lanthanide series metals and the alkaline earthmetals.

The reason for this is because they have a stronger metallic bonding between their atom.

Hardness is a physical property which is attributed to intermolecular forces and the atomic arrangement

The transition metals are found in the d - block on the periodic table.

They have a d-orbirtal which confers extra electrons and higher degree of stability to the atom. The d-orbirtal provides more delocalized electrons for the metallic bonds formed.

Answer:

The answer is D), transition metals

Explanation:

I searched it up, and the only metal with hardness showing as a significant property was transition metals. I took the test, and transition metals is the answer. I also pulled this up on the internet:

Transition metals are hard which indicates the presence of covalent bonds. This happens because transition metals have unpaired d-electrons. The d-orbital which contains the unpaired electrons may overlap and form covalent bonds. Therefore, these transition metals are very hard.
