A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.
How do green leaves make energy?Green leaves are producers. They contain a pigment named chlorophyll which helps to trap sunlight which is required by the leaves to make food, and this process is called photosynthesis.
Green leaves take carbon-di-oxide, sunlight, and water, and in the presence of chlorophyll, glucose is produced and oxygen is released as a by-product. This process takes place in the chloroplast. There are four steps involved in photosynthesis that is Absorption of light, transfer of electrons, ATP production and carbon fixation,
These leaves are consumed by primary consumers such as Weebugs, and they get energy. A decrease in green leaves can decrease the number of Weebugs. Hence, option B is correct.

Answer:
D. To show condensation, you add energy to change water vapor into liquid water; to show evaporation, you add energy to change liquid water into water vapor.
When condensation occurs, gas turns to liquid, and when evaporation occurs, liquid turns to gas.
B. could also be correct, but D. seems to be the better fit.
Answer:
To show condensation , you must decrease the temperature within the cycle ; to show evaporation , you must increase the temperature .
Explanation:
Condensation : condensation is nothing but the change of water vapour into liquid water . it happens when the water vapour reaches from a hot area to a cold area . for instance ~ when you pour hot tea in a cup and cover it with a plate. after few seconds you would see droplets of water there . this means that the water vapour which was in liquid form , when touched the cold surface of plate , it changed into liquid water .
Evaporation : It is the conversion of hot liquid into water vapour . just reverse of above phenomena .

A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.
Answer:
Option B, He should conduct tests using computer models to determine the safety impact.
Explanation:
The better performance of material proposed by engineer will be treated as a claim without any proof, if the production of the stake board starts without testing it.
In order to verify his/her statement, the engineer needs to conduct durability and strength test on stake board having the “proposed material” in its structure.
After the test results are obtained, they must be vetted through publication as research paper.
Hence, option B is correct

Answer: B
Explanation:
• Nerve cells (neurons) carry the message from the stimulated receptors to the correct effectors.
• A sensory neuron carries the message from the receptor to the central nervous system (the spinal cord and brain).
• A motor neuron carries the message from the central nervous system to the effector.

Which statement best describes Mendel's law of dominance?
O
A. Each parent of an offspring contributes two factors for each of the
offspring's traits.
B. The separation of two factors for one trait will always affect the
separation of another trait's factors.
O
C. Inherited traits are controlled by two factors that separate during
reproduction.
D. Only one of the two factors that control a trait is expressed when
both types of factors are present.
Only one of the two factors that control a trait is expressed when both types of factors are present best describes Mendel's law of dominance. Thus option D is correct.
what is Mendel's law?
According to Mendel’s Law of Dominance When an organism is mixture of heterogeneous trait, it expresses allele which are dominant, here the dominant trait always masks the recessive trait.
The trait is present in the form of two allele and one allele is dominant over the other allele which is recessive.
The dominant allele contributes exclusively to the phenotype of the offspring and Dominance can also be described as when one of the two alleles is non-functional means it does not produce a functional protein.
The recessive trait will be expressed only when both the allele are present in homozygous form from both parents.
Thus option D is correct.

Consider the food web seen here. One member, the northern spotted owl, lives in cavities of trees in old-growth forests. Old
growth forests contain trees that are more than 200 years old and have not been cut, pruned, or managed. Imagine that these
forests have been heavily logged, Predict the outcome on this food web if the habitat of the owl is removed
AY
The food web will collapse without this top-level consumer present
B)
The niche filled by the owl will be filled by other predators like the hawk
and fox
The niche filled by the owl will be empty. The other animals within the
food web will grow unchecked.
Without the owl present, the empty niche will result in an overpopulation
of hawks. Eventually the lower-level consumers will disappear
DY
Answer:
I'm pretty sure it is the third option: The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
Explanation:
The owl is a predator animal. As it hunts small prey, it keeps the population of those prey animals stable. If the owl is taken out of the habitat, then the population of the prey animals it used to hunt will grow out of control.
The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.
What is a food web?All the food networks in a single ecosystem make it into a food web. Each organism in an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as they move through the environment. A food web is made up of all the linked and overlapping food systems in an ecosystem.
The trophic levels are divisions into which organisms in food webs are categorized. These levels can be roughly categorized as producers (first trophic level), consumers (second trophic level), and decomposers (final trophic level).
The first trophic level is producers. Producers often referred to as autotrophs, produce all of their own food and do not rely on any other living thing for sustenance. The majority of autotrophs convert sunlight, carbon dioxide, and water into food (a nutrient called glucose) through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live near active volcanoes make their own food by using sulfur rather than carbon dioxide. Chemosynthesis is the name of this process.
Therefore, The niche filled by the owl will be empty. The other animals within the food web will grow unchecked.

Answer:
Protecting different kinds of wildlife.Restoring vegetation in certain areas.Ensuring improvement of environmental health.Relocating ecosystems away from polluted areas.Explanation:
These are all the factors that are included in watershed conservation. Watershed conservation is very important to the environment for several reasons. Freshwater from the watershed is often used by people for the purposes of drinking, cleaning and bathing. Conserving this source allows us to avoid the depletion of freshwater supply. Moreover, it is important to ensure that such water is not polluted, both for the benefit of humans, as well as to ensure that plants and animals that require this water are able to access it safely.

of her gametes will carry the allele for dimples?
A. 0%
B. 25%
C. 100%
D. 50%
Answer:
50%, i believe
Explanation:
So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.

Answer:
The mice population would be lowered, and that predator could be a prey to other predators in that environment.
Explanation:
The introduction of new predator has both positive as well as negative effects on the ecosystem and environment.
What happen when the predator in introduced in an ecosystem?If a new predator was introduced into the ecosystem that only ate mice so this results in the reduction of population of mice which leads to the disturbance of the ecosystem.
