1. spherical
Answer: d. cocci
A bacteria with spherical shape would be called cocci or coccus if they are in coccus in a group. One of the examples would be Staphylococcus aureus which is one of the normal flora of the skin. The word staphy- describe how their colony shaped which is look like grapes.

2. rod-shaped
A bacteria with rod-shape would be called bacilli or bacillus if they are in coccus in a group. One of the examples would be Bacillus anthracis which is a pathogen that could do deadly infection called anthrax. Many other bacteria is not named bacillus but have rod-shape like Escherichia coli, one of normal flora in the human gut

3. purple stain
Answer: gram-positive 
4. pink stain
Answer: gram-negative 

In gram staining procedure, bacteria can have either purple or pink color. If the bacteria have high amount peptidoglycan in their membrane, they can retain the crystal violet color from the staining procedure. Bacteria with a high amount of peptidoglycan will be called gram-positive bacteria.
If they are not, the alcohol will remove the stain, allow the bacteria to retain safranin or fuchsine pink color. Bacteria with a low amount of peptidoglycan will be called gram-negative bacteria.

As part of their normal function, many proteins bind to DNA briefly and then release it again. Which types of interactions might

Harman [31]

Answer:

Non-covalent interactions.

Explanation:

DNA is present as genetic material in all the living organism except some viruses. DNA also perform important other functions - code for proteins, used as a source of energy.

The DA binds with protein to perform their functions. These proteins may acts as activator for DNA. The proteins binds in the non covalent interactions ( ionic bonding, hydrogen bonding, vanderwalls and hydrophobic interaction) so that proteins may easily detach from the proteins. These interactions helps in the attachment and easily detachment of proteins from DNA.

Thus, the correct answer is non-covalent interaction.

Coat color in a dog breed is determined by incomplete dominance where three colors are produced (Brown, tan and white), and the

8_murik_8 [283]

Genotypes of the dog color are:

BB dominant homozygous-brown phenotype

bb recessive homozygous-white phenotype

Bb heterozygous-tan phenotype

Cross between brown and pan dog would be:

P: BB x Bb

F1: BB Bb BB Bb

The ratio would be 1:1 (brown dog:pan dog).

Give one example of how the testing of Platismatia glauca could benefit future ecological research of this forest.

storchak [24]

Answer:

Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

hope this helps:)

Explain the relationship among

Iteru [2.4K]

Answer:

There is an important relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.

Explanation:

There is a great relationship among homeostasis, defective mitochondria and the symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

At the end of _____ and cytokinesis there are four haploid cells. At the end of _____ and cytokinesis there are four haploid cel

kotegsom [21]

Answer:

At the end of telophase II and cytokinesis, there are four haploid cells.cells.

Explanation:

During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.

We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
