Answer:

Gram positive; Contain thick mesh wall of peptidoglycan in cell wall.

Explanation:

Gram staining technique is used to separate the gram positive and gram negative bacteria on the presence or absence of thick layer of peptidoglycan in cell wall.
If a bacteria contain thick layer of peptidoglycan in cell wall it will retain the primary stain crystal violet (purple) and known as gram positive bacteria.
If bacteria don't have thick layer of peptidoglycan in cell wall the stain will wash out and it will give the pink color known as gram negative bacteria.
Peptidoglycan is glycoprotein or Glucose+Protein.

Ahominine can use both hands to carry an object from one place to another because it does not need its hands for locomotion

Romashka-Z-Leto [24]

If the choice is true or false, the answer is true. Most of hominins were probably nearly as efficient at bipedal locomotion as humans. However, the bones of their pelvis were shorter from top to bottom than humans. This made their pelvis more stable for weight which supports standing upright or moving bipedially.

Where is the protein on a DNA?

QveST [7]

Answer:

Explanation:

The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.

Which of the following does NOT occur in cells? Group of answer choices The conversion of sunlight into energy stored in chemica

seraphim [82]

Answer:

The use of heat to burn foodstuffs

The use of chemical energy to transport organelles through the cytosol

Explanation:

In plant cells, sunlight energy is converted into chemical energy in a process known as photosynthesis which happens in the chloroplast.

During respiration, cells generally metabolize nutrients to produce useful energy in the form of ATP.

<em>Heat is not used to burn foodstuffs in any cell while organelles are not transported through the cytosol in any cell.</em>

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of

natali 33 [55]

The correct option is (a) 2 → 4 → 1 → 3

A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.

<h3>What is genetic variation in population?</h3>

The presence of various alleles, or different gene versions, within a population indicates genetic variety.
If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
