A unique substance composed of atoms having the same atomic number
Answer:
Element
Explanation:
An element is made up of a single type of atom, that is, it’s a substance made up of atoms that have the same number of protons in the nucleus, this number is known as the atomic number of the element. An atom is the smallest particle of an element that retains its properties.Each element is made up of atoms with the same chemical properties such as reactivity, ionization potential. Chemical elements are identified by names given in antiquity, derived from some property of them, from the name of their discoverer, from the place of discovery. In nature there are 92 elements that can be presented (at 1 atm of pressure and 25 ºC) as solid: iron, lead; liquid: bromine, mercury or gas: chlorine, oxygen.
Cystic Fibrosis is a homzygous recessive disease that affects 1 in 3400 people. What percent of the population are carriers?
Answer:
The correct answer is = 0.02 or 2.5 percent approx.
Explanation:
Given:
CF is a recessive disease that affects 1 in 3400 people
The frequency of the recessive allele in the population (q2) -
= 1/3400
= 0.0002. Therefore, q is the square root, or 0.014.
The frequency of the dominant allele in the population (p)
= 1 - 0.014 = 0.986 (or 98.6%).
The percentage of s carriers in the population.
2pq equals the frequency of heterozygotes or carriers, then the equation will be as follows:
2pq = (2)(.986)(.014) = 0.02 or 2.5 percent approx.

Identify the most efficient way to protect biodiversity.
Explain your reasoning.
**please do not put the sample response :) **
Protecting habitats before they are torn down.
or
we can consume less and be more mindful about what we consume.
The efficient way to protect biodiversity is to protect plant and animal species that are extinct day by day and minimize the effect of pollution on the environment.
What is biodiversity?Biodiversity is the diverse living things and nonliving things present on the earth. Biodiversity refers to the different species of plants and animals that live and interact with each other, and they are also dependent on each other.
Nature is interdependent, every organism depends on another organism for its living and the dance of the autotrophs gives energy to animals.
It is important to protect biodiversity because if animals and plants while extinct other animals can as also be living.
Thus, the most effective strategy to preserve biodiversity is to safeguard the rapidly disappearing plant and animal species while reducing environmental degradation.

the carbon cycle, photosynthesis, and cellular respiration and show how they are connected/work together in an ecosystem. Play the role of a carbon atom in an ecosystem. Start with the production, how are you made? And then explain how you transform through different processes. Make sure to include your role in the carbon cycle, photosynthesis, and cellular respiration. There is no set length, as long as you explain the role of carbon in each process.
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere.
What do you mean by cellular respiration?Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.

A controlled experiment _____. Group of answer choices Includes at least two groups, one of which does not receive the experimental treatment Is repeated many times to ensure that the results are accurate Proceeds at a slow pace to guarantee that the scientist can carefully observe all reactions and process all experimental data Includes at least two groups, one differing from the other by two or more variables
Answer:
A. Includes at least two groups, one of which does not receive the experimental treatment
Explanation:
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Also, an experimental group can be defined as a collection of participants that are subjected to the independent variable.
Generally, most scientific experiments usually have a control group so as to avail the scientists (experimentalists) an ability to compare the outcome of their test results. This control group is not given the treatment or influenced by the same independent variable as the experimental group.
Therefore, this is the reason why science completely or totally rejects any hypothesis which is not supported by observations, as well as the results obtained from control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.
Hence, a controlled experiment includes at least two groups, one of which does not receive the experimental treatment.
A controlled experiment includes a control group and at least one experimental group. Option A). A controlled experiment includes at least two groups, one of which does not receive the experimental treatment.
In a controlled experiment, the researcher wants to identify the effect of one or more variables on something.
Since many different variables might be affecting the results, and most of them are not of interest to the researcher, they must be kept under control. They must remain constant.
There must be at least two groups. One of them must be the control group, and the other one (or other ones) is the experimental group.
During an experiment, the researcher compares the two groups. Both of them are composed of individuals coming from the same population, so they are identical in all aspects except for the independent variables that the researcher changes in the experimental group to observe how they affect the individuals.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment. The independent variable keeps constant in the control group. The experimental group receives the treatment. The researcher voluntarily changes the values of the independent variable to observe how it affects the individuals subjected. There can be several experimental groups.
Hence, A controlled experiment includes at least two groups, one of which does not receive the experimental treatment.

Can Chromatin be called a process?
Answer:
I believe it could be called a process.
Explanation:
DNA wraps itself around histone proteins to form nucleosomes and the beads on a string structure. Multiple histones wrap into a 30-nanometer fibre consisting of nucleosome arrays in their most compact form. The higher-level DNA supercoiling of the 30-nm fiber produces the metaphase chromosome. Which occurs during Mitosis and Meiosis. There are some chromosomes that do not follow this alignment. The overall structure weighs on the stage of the cell cycle.

Which type of human cells contain a half set of chromosomes (often written as n)?
Answer:
Gametes are the type of human cells that contain a half set of chromosomes.
Explanation:
In superior organisms that reproduce sexually, such as human beings, the somatic cells are diploid (2n), which means that each cell has a pair of equal chromosomes. The somatic cells are all the body cells excepting for the sexual ones, and they reproduce by the process of mitosis. These cells have a set of chromosomes inherited from the maternal side and another homologous set of chromosomes inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells are diploid, 2n.
In humans, there are also sexual cells, which are haploid (n). These cells are the gametes, and they reproduce by the process of meiosis. Gametes contain half the number of chromosomes that might be found in the somatic cells. The number of chromosomes in this set is haploid, n.
