during meiosis, a single male germ cell will produce ______ sperm, whereas a single female germ cell will produce _____ egg.
Answers
Answer:
The correct answer is : 4 sperms, and 1 egg.
Explanation:
Germ cells are the cells that have ability to divides in to gametes that will fused with the gametes of opposite sex to reproduce sexually and produce offspring.
Meiosis is one of the cell division process where one cell goes under the division twice to make four cells with the half of the genetic content than the parent cells. These cells are gametes or sex cells known as sperm in males, eggs in females.
In this process germ cells go under division twice to produce four daughter cells that are haploid, in males these cells are called as sperms, whereas in females the three cells become polar bodies and the fourth cell termed as egg.
Thus, the correct answer is : 4, and 1.

A blow to the cheek is most likely to break which superficial bone or bone part? (a) superciliary arches, (b) mastoid process, (c) zygomatic arch, (d) ramus of the mandible
Answers
Answer:
The correct answer is option c, that is, zygomatic arch.
Explanation:
In anatomy, a section of the skull produced by the temporal bone’s zygomatic process and the zygomatic bone’s temporal process is known as the cheekbone or the zygomatic arch. Temporal bone refers to a bone, which protrudes frontward from the skull side, that is, over the opening of the ear, while the zygomatic bone is the lateral to the cheekbone.
When a blow takes place to the cheek then the superficial bone or the part of the bone that breaks most likely is the zygomatic arch.

DNA Ligase is responsible for: A. adding the new bases. B. keeping the strands separated during replication. C. linking the short sections of the lagging side. D. unwinding and separating the DNA strands.
Answers
☯️ The DNA ligase is responsible for :
Linking the short sections of the lagging side.Explanation:-The ligase is a enzyme responsible for the linking or joining of short sections or strands. It connects the strands by forming a bond between the phosphate group of one DNA strand with deoxyribose group of other.
It is also used in Okazaki fragments connection which are formed in the lagging side during DNA replication. So, We can say that DNA ligase is a specific enzyme which helps in the linking and connecting the DNA strands or fragments by the formation of phospodiester bond[tex].[/tex]

Water molecules are polar. Explain the distribution of charge in a molecule of water.
Answers
Answer:
Water is a "polar" molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atom.Water molecules are polar because it determines the bent shape of the molecule in which the partial negatively charged atoms are covalently bounded to the partial positively charged hydrogen atoms.
What are the other characteristics of water molecules?The other characteristics of water molecules are as follows:
It acts as a universal solvent.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.
This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.
Therefore, it is well described above.

a) Antonie Van Leeuwenhoek is considered to be the first microbiologist. His work was completed before Pasteur's. He was the first to use microcscopes to observe and describe single-celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. How did Van Leeuwenhoek's work provide the basis for Pasteur’s work on disproving the theory of spontaneous generation? (4 points)
Answers
Answer:
Explanation:
The spontenous genrration theory states that living organisms can be spwan without descent of similar organisms; so in other words, it is possible for living creatures could arise from nonliving matter such as water. Similarily in 1676 Van Leeuwenhoek discovered tiny organisms living in his cup of water- the first bacteria observed by man. Pasteur's spontenous generation theory came into the limelight after his most noteable experiment in 1859; in which he boiled meat broth in down ward tipped flasks. It is importnat to note that the tip of the flask (the neck) is what prevented particles to fall freely and instead the bent neck allowed air to travel through the flask- if the flask were to be tilted on its side the particles would seep into the broth and create a cloud within the flask. Pastuer further decided to boil the broth to possible create bacietia. Boiling the broth exposed the contents to air vessels which contained a filter to stop the particles from seeping thorugh into the broth. What Pastueru concurred from his experminet was that flasks with filters and no filters that did not allow the particles to pass into the medium of the flask, were unsucessful with createing bacteria life. Thus, Pasteur found that noithing grew in the flasks unless they were broke open, disapproving that living organisms could be spotenously generated within the broth, was instead created from outside the inards of the flask- and were created as spores or dust.

A learner was walking along a road when she saw an object under a tree. When the learner touched the object, it rolled over and divided into two . Which characteristics of living organisms did the object show?
Answers
Answer:
growth, reproduction, and sensitivity
Explanation:
The characteristics of living organisms displayed by the object are growth, reproduction, and sensitivity.
When the organism reacted by rolling over in response to touch from the learner, it was displaying sensitivity. Sensitivity has to do with the ability of living organisms to be sensitive to things such as touches.
When the object divided, it was displaying growth and reproduction that are characteristics of living organisms. Growth can be defined in this case as an irreversible increase in the number of cells and reproduction can be defined as the production of new individuals.
By dividing into 2, the object has increased its number of cells and has also produced a new individual.
Hence, the characteristics of living organisms shown by the object are growth, reproduction, and sensitivity

Atoms make up every substance around you is the true statement. Therefore, option (D) is correct.
What are atoms?An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.
Moreover, at the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.
Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive.
