Answer:
The correct answer is -
1. protein synthesis or central dogma
2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.
Explanation:
1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.
2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

both plants and animals
none of the above is correct
Not sure but i think its plants
Both plants and animals store some of the molecules from food in their bodies to use later as a source of chemical energy and building materials.
One of the important characteristics of living organisms is metabolism. Living organisms are able to obtain food which is stored as various chemical substances in the body.
This food materials that are stored as chemical substances are later broken down to produce the energy required by the organism to carry out its activities. Both plants and animals store some of the molecules from food in their bodies to use later as a source of chemical energy and building materials.

Explanation:
Which type of growth can occur only when a population has unlimited resources?
limited
logistic
exponential
negative
Answer:
c. on edge
Explanation:
When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. The correct answer is c) exponential.
What is the exponential growth curve?Exponential growth curves and logarithmic growth curves are the two different forms of growth curves. In an exponential growth curve, the slope increases steadily over time. A logarithmic growth curve has a steeply increasing slope that gradually flattens out over time.
The exponential growth curve, which has a J-shape, shows a period of time where the results develop rapidly and steadily. It is the reverse of gradual progress. This curve initially climbs gradually before accelerating, which represents multiplied growth.
With exponential growth, a population's growth rate per capita (per person) remains constant regardless of population size, causing the population to expand exponentially as it grows larger. In nature, populations may expand exponentially for a while, but ultimately, their growth will be constrained by the availability of resources.
Exponential expansion happens when resources are unrestricted. Due to the favorable conditions, there are a lot more births as a result of the food excess.
Therefore, the correct answer is c).

Cutting down trees in a forest alters the habitat of the organisms living in the forest. The given statement is true.
What is habitat?
Habitat is known as the place where the animals lives and survive the place is known as the habitat. Cutting down the trees is known as the deforestation. The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

Explanation:
Every organism requires a set of instructions that specifies its traits. This information is carried with the cells of the organism. Which set of statements BEST describes hereditary information in eukaryotic cells? Group of answer choices
Answer:
This question lacks options, the options are;
A. Genes are made up of chromosomes and both are found in the cell’s cytoplasm.
B. Chromosomes are made up of genes and both are found in the cell’s cytoplasm.
C. Genes are made up of chromosomes and both are found in the cell’s nucleus.
D. Chromosomes are made up of genes and both are found in the cell’s nucleus.
The correct answer is D.
Explanation:
As rightly stated in this question, every living organism requires a set of instructions that specifies its traits. These set of instructions are embedded in a unit called GENE. Genes hold information needed for the survival of a cell in an organism.
These genes are located on a structure called DNA, which are folded or packaged into another structure called CHROMOSOMES. Each chromosome, hence, contains genes that are the unit of inheritance of a cell. In eukaryotic organisms, the gene is found on a chromosome, which is located in the NUCLEUS of the cell.

In a moth population, 47 are brown, 15 are yellow, and 34 are black. What is the approximate probability of a moth being black?
A. 2%
B. 49%
C. 16%
D. 35%
Answer:
D
Explanation:
34/96= 35%
The mathematical rule of three can be used to take probabilities. In the exposed example, the approximate probability of a moth being black is 35% (Option D).
------------------------
Available data:
47 moths are brown15 moths are yellow34 moths are blackThe total number of individuals in this population equals the addition of brown, yellow, and black individuals.
This total number of individuals equals 100% of the population.
So to get the probability of a moth being black, we can just perform a rule of three.
To do it, we need to get the percentage of black individuals in the current population.
96 moths ------------------------- 100% population
34 black moths ----------------- X= (34 x 100) / 96
=35.41 ≅ 35% of the population

ecosystem contain both blank and blank parts
Explanation:
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.
What role does the ecosystem play on Earth?There are numerous ecosystems on Earth, each with its own set of functions and living forms, but these are essential for human survival as they support a wide variety of plant and animal species, thus maintaining the biodiversity of the earth. By absorbing and storing carbon, forests, oceans, and wetlands help to regulate the earth's climate by managing the carbon cycle and regulating the climate.
Hence, every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.
