Genes is found in the DNA. It decides a specific characteristic. Genes can transform and take two or more option structures and these structures are called Alleles. Presently allele happens in an altered spot in a chromosome and in people we have two arrangements of chromosomes.

There are 46 chromosomes in the human. 23 from the dad, 23 from the mother = 46 chromosomes.

Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.
timurjin [86]

Answer:

An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

Explanation:

An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.

So, an example of this applied to bacteria or viruses could be:

<u>An experiment where an antibiotic is tested against bacteria</u>. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.

To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

Carbohydrates are the primary source of energy for the huma
Xelga [282]

Answer:

Ambitious

If your body lacks enzymes that break down

carbohydrates, it would be unable to get sugar molecules for energy production.

If you lacked the enzyme to digest proteins, you may not absorb enough amino

acids.

The digestive system in our body changes

carbohydrates into glucose; also known as blood sugar to be use as an important

source of energy. Meanwhile, amino acids are organic compounds that combine to

form proteins, which are the building blocks of life.

What are the loosely packed photosynthetic cells in the leaf called? A. epidermis B. guard cells C. spongy mesophyll D. palisade
Karolina [17]

Answer: Option C

Explanation:

These cells are soft because of its function. Gaseous exchange takes place by the help of these cells. Spongy mesophyll cells are covered by thin layer of water and are loosely packed.

This is because, during the day time when the plant is performing photosynthesis these cells allows the carbon dioxide into the mesophyll cells and the oxygen out of the plant body.

Why accurate biological drawings are more valuable to a scientific investigation than an artistic approach?
viktelen [127]
Scientific drawing is made-up to be precise and founded on real living things or fossils. Artistic drawings do not have to have any origin in realism and it can be abstract and it does not have to tolerate any similarity to any real life object. Artistic drawings are not unavoidably meant to be a faithful reproduction of anything in nature even though that was once the aim in the distant past before the invention of photography. Constructing good biological drawings be situated significant in that they aid to develop more accustomed with the topic over vigilant consideration to the smallest feature. Drawings allow to progress observational skills which is the principle of good science. Good drawings are those that abridge, highlight, review, and explain all at once. For these explanations, consideration to the smallest feature is precise significant. Biological drawings are not destined to be artistic masterpieces but are more like graphic notes that help record a set of observations. As such, these observations must be accomplished in class with the specimen directly observable.
