Explanation:
Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth's continents were once part of an enormous, single landmass called Pangaea.
Answer:
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

Hypersecretion of growth hormone after normal growth has ceased may cause
acromegaly
achondroplastic dwarfism
pituitary dwarfism
gigantism
Answer:
gigantism
Explanation:
The growth hormone is responsible for stimulating normal growth in humans or in other words, stimulating growth at a normal pace. To do this, the growth hormone must be released in optimal quantities, however, an hypersecretion i.e. excessive release of the hormone will cause a fast and uncontrollable growth in certain regions of their body or the whole.
This abnormal excessive growth caused by an excessive release of the growth hormone is called GIGANTISM. Gigantism occurs mostly in children at their growing phase.
why RNA is always single stranded and DNA is double stranded
Answer:
The DNA is very stable in it's double helix form. RNAs are relatively unstable and easy to degrade because they are single stranded. They are single- stranded so that translational proteins may read then and produce proteins.

Answer:
Prostate CancerTesticular CancerMale infertility Testosterone Deficiency Enlarged prostate or BPHWhich of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.

Answer:
Forming adhesive trapping nets.
Explanation:
These modifications are important to captured its food and to survive in the environment. Unique feature does Arthrobotrys have is the presence of predatory behaviour. Due to this predatory behaviour of Arthrobotrys, they are able to capture the food such as nematodes and feed on them. The Arthrobotrys belongs to the fungi family Orbiliaceae and have 71 species. This fungi formed adhesive trapping nets in order to capture its food.
hich statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.
Answer:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

l. A farming area developed a major locust problem. Swarms of locusts were destroying crops and the environment. A team of
scientists developed an infectious disease that would reduce the population of locusts What would be most important to find
out before producing and releasing the disease?
how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
What is Population?This is referred to the number of organisms present in an area over a
specific period of time.
We were told that swarms of locusts destroyed the environment and
needed to be reduced through the creation of a disease. The effect the
decrease in locust has on other organisms has to be considered to ensure
the ecosystem is balanced and doesn't adversely affect others.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:
Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.
Answer:
If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.
Explanation:
Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.
The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.
When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:
Dominant RecessiveWhen one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.
Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.
Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.

Choose the CORRECT statement about enzymes below.
Group of answer choices
Enzymes raise the activation energy needed in a chemical reaction
Enzymes slow down the rate of chemical reactions
Enzymes function best at specific pH and temperatures
Enzymes are carbohydrates and store short term energy
Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
