What is an atom’s atomic number? the number of electrons in an atom the number of neutrons in an atom the number of protons in an atom the number of bonds in an atom

Answer:

Explanation:

Industrialization and use of combustible engines for daily life activities by humans has led to the production and release of a large amount of greenhouse gases (such as CO₂, N₂O, CH₄ and CFC) into the atmosphere-which prevents a large amount of heat produced from the earth moving to space.

The burning of fossil fuels by combustible engines (from cars, trains, power generating sets e.t.c) widely used by humans has led greatly to this climate change. Trees that help absolve a large amount of the most abundant man-made greenhouse gas (CO₂) has not been massively planted around, which indirectly worsens the case of global warming. Trees would have absorbed/breath in the CO₂ while producing/breathing out O₂ that could help cushion the effects of global warming.

Microfilaments

Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.

Microtubules

Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.

Answer:

Computional model, used to study an outbreak of an infectious disease called influenza.

Answer:

1-  Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.

2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.

3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.

Explanation:

The respiration which uses oxygen is called aerobic respiration. In aerobic respiration, the glucose food is completely broken down into carbon dioxide and water by oxidation. Aerobic respiration produces a considerable amount of energy for use by the organism which gets stored in the ATP molecules.

Studying the genetic ancestry of humans can help explain why some people have a higher or lower risk of certain diseases. Finding the genes related to certain diseases will help fuel new drugs and therapies. For example, the article explains that people with six copies of CLPS genes seem to have a lower risk of diabetes

Explanation:

According to me, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.

Genetics may be defined as the branch of biology that deals with the study of heredity and variations that are remarkably controlled by genes.

The genetics of dead organisms reveals the process and methodology of past organisms. It illustrates how the differences in present organisms lead to the process of evolution.

It compares the physiology, psychology, genomic sequencing, alterations in the genetic arrangements, etc. It also allows us to understand new facts and changes that fascinate evolutionary questions.

Apart from this, modern technology makes the study of dead organisms more effective and significant with numerous benefits like recombinant DNA technology, DNA analysis, isolation, etc.

Therefore, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.

Answer:

Hmm.

Explanation:

A group of independent organisms in a particular environment​ are called a community.

Answer:

The answer is the second option: Dependent variable, experimental group and control group

Explanation:

Let's list out all possible variables/groups in the option

Independent variable: This is a variable that is intentionally (directly or indirectly) altered by the one doing the experiment but is not affected by any variable/group during the course of the experiment. No Independent variable was mentioned.

Dependent variable: This is a variable that is affected by another variable and is usually the variable been tested during the course of an experiment. The dependent variable here is the effectiveness of a new nutrient supplement.

Experimental group: This is the group that is being treated during the course of an experiment. The experimental group here is the group of identical mice given the supplement.

Control group: This is a reference group that is not given any treatment during the course of an experiment. The control group here is the group of identical mice not given anything.

From the above description, it can be deduced that the parts of the experiment described in the scenario in the question is dependent variable, experimental group and control group.

Answer:

B  :)

Explanation:

for people who speed run

Answer:

Independent variable: Different products of toothpaste

Dependent variable: Amount of plaque left in her teeth

Control group: Water

Constant: Same amount of time for product to have an effect

Explanation:

Independent variable is the variable that is subject to manipulation or change by the experimenter in order to effect a measurable response. The independent variable in this experiment is the DIFFERENT PRODUCTS OF TOOTHPASTE USED.

The dependent variable is the variable that is measured during the experiment. In this experiment, the dependent variable is the AMOUNT OF PLAQUE LEFT IN ALEX'S TEETH.

The control group in an experiment is the group that does not receive the treatment/independent variable. In this case, the usage of WATER is the control.

The constant is the variable kept the same for all the groups in the experiment. In the case, the Same amount of time for each product to have an effect on her teeth is the CONSTANT.

Explanation: because of real time

Answer: Place each oil stain on separate, but identical, pieces of cloth.

The group of students should have stained separate but identical pieces of cloth.

There are different factors that influence how easily a stain will come out of a material such as:

Assuming the temperature is held constant and the type of detergent is being tested, the only thing other thing to control is the type of material.

The students used separate cloths instead of identical ones which meant that a significant variable was not controlled.

In conclusion, the students should use separate but identical pieces of cloth so that the type of material would not impart their experiment.
