Explanation:
wild animal attack is which type of disaster
(a) biological
(b) geological
please help me
Wild animal attacks should qualify as biological disasters rather than geological disasters.
Disasters generally refer to accidents that happen rather suddenly and result in widespread damages or loss of lives
Biological disasters are disasters whose causes have biological origins such as plants, animals, humans, and microbes.Geographical disasters are caused by natural geographical events such as landslides, cyclones, hurricanes, volcanic eruptions, and so on.Wild animals are biological organisms, hence, an attack from them would be a biological disaster.

What are chromosomes?Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. When chromosomes cross over happens, the alleles changes and a new combination produces.
Therefore, the correct option is d. generating new combinations of alleles.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature can also affect a plant (B) As with any living thing, a plant has an optimal temperature range at which it grows and preforms best (C) It may not be able to take in enough water and nutrients through it's roots (D) Too much heat can cause plant cells to break down, a process called denaturation.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

Which one of the following factors does NOT affect Earth’s climate?
A. Ocean Currents
B. Energy from the Sun
C. Elevation
D. Soil Composition
Answer:
D
Explanation:
its just not any other one
Our soil cleans our water, feeds our trees and crops with vital nutrients, and controls numerous significant greenhouse gases in addition to helping to maintain the Earth's temperature. Thus option D is correct.
What is the soil impact on Earth climate?On a smaller scale, soil can also affect climate. More so than drier, looser soils, wetter or denser soils hold heat and stabilize the environment from temperature variations.
In deserts, the temperature can rise by more than 60 °F in a single day. The largest repository for terrestrial carbon is healthy soil. In the carbon cycle, soils are essential because they absorb carbon from decaying plant tissue.
By storing carbon (carbon sequestration) and reducing greenhouse gas emissions in the atmosphere, soils can be effectively managed to mitigate climate change.
Therefore, soil composition factors does NOT alter Earth’s climate.

If all cells in your body contain the same DNA why do they perform different functions. Pls help
Answer: These cells are different because they use the same set of genes differently. So even though each of our cells has the same genes, each cell can select which ones it wants to "turn on" and which ones it wants to keep "turned off". So when everything is working properly, each cell type only reads the genes it needs.
Explanation:
They are differentiated based on the genes that's why they perform different function.
it involves a switch from one pattern of gene expression to another. What are genes? Gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called.Many genes do not code for proteins.To know more about genes here

Answer.
Type your answer her to focus a microscope using the high-power lens you have to use the focus adjustment
knob but be careful because if you crank down too hard you can damage the microscope and the slide
Is my answer right
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.

Photosynthesis and respiration recycle carbon in plants. Animals get carbon from plants and exhale it. Therefore, option (B) is correct.
What is carbon cycle?The biogeochemical process known as the carbon cycle involves the transfer of carbon between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the most common element found in organic compounds, and it also plays a significant role in the chemical makeup of numerous minerals, including limestone.
Through the process of photosynthesis, plants take in carbon from their surroundings and then release it during the process of respiration. Plants are the source of carbon for animals, and animals exhale carbon during the process of respiration.
Therefore , option (B) best explains the roles plants and animals play in recycling carbon.
