Answer:
1.El aparato excretor se encarga de expulsar de nuestro cuerpo los desechos. Para ello utiliza el sistema urinario y las glándulas sudoríparas. El sistema urinario filtra la sangre para limpiarla de desechos y produce la orina. Las glándulas sudoríparas producen el sudor y regulan la temperatura de nuestro cuerpo
2.Su función es eliminar mediante un proceso de filtración los productos de deshecho resultantes del metabolismo celular o incorporados desde el medio ambiente, por ejemplo durante la alimentación, exceso de sal en las aves marinas, etcétera. El principal sistema de excreción en los animales es el sistema urinario
3.La excreción en plantas es para extraer sustancias que luego pueden ser utilizadas por ellas mismas para realizar sus funciones de fotosíntesis y de respiración, o bien, acumularla en sus vacuolas para sustancia de reserva. ... Se pueden acumular en vacuolas o espacios intercelulares
How does electricity impact the society for better or for worse?

Describe three characteristics of enzymes
Answer:
1.They act as a catalyst
2.Enzymes are proteins
3.They are affected by Ph
4.They are affected by temperature
Explanation:
1.Enzymes act as a catalyst because they either speed up or slow down the rate of a reaction
2.They are proteins because they are made up of 20 amino acids
3.Enzymes are affected by temperature, if the temperature increases, the reaction rate increases. However if the temperature continues to increase, the shape of the active site changes.If the temperature is below preffered temperature range,the rate of the reaction becomes slower,but the shape is not denatured.

Amphetamine is a drug that suppresses appetite in most animals. To study the magnitude of this effect in rats a scientist randomly assigned thirty rats into three treatment groups to receive either a dose of amphetamine (2.5 or 5.0 mg/kg) or a control (saline, 0 mg/kg). Then food consumption was measured in grams per kilogram of body weight (g/kg) for the three-hour period after the injection.

The four main types of biomolecules are carbohydrates, lipids, proteins, and
O nucleic acids.
o sugars.
O fatty acids.
O amino acids.
Answer:
the answer is nucleic acids
Explanation:
The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids. Thus, the correct option for this question is A.
What are Biomolecules?Biomolecules may be defined as those types of molecules that are significantly present in the body of living organisms and are required to perform essential functions like cell division, morphogenesis, or development.
The four types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are energy-deriving organic molecules that provide immediate energy for the cells to perform metabolic activities.
Proteins are required for the structural arrangement and absolute function of cells. Nucleic acids are required for synthesizing the genetic material of an organism. While lipids store energy.
Therefore, the four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids. Thus, the correct option for this question is A.

What is an effect of the reduction in bird populations?
Answer:
There will be new niches formed as the birds remaining have to adapt to living with smaller population. There is a likely chance that they will develop changes in beak size and shape. The predators of these birds will have to adapt onto using a different food source, the birds may migrate to a safer area... or, theres a possiblility that the birds will simply go extinct!

Determine whether the following statement is true or false and why. “Variation caused by the environment is not heritable, so it is not subject to natural selection.”
A. True
B. False, it should read “Variation caused by the environment is heritable, so it is subject to natural selection.”
C. False, it should read “Variation caused by the environment is not heritable, so it is subject to natural selection.”
D. False, it should read “Variation caused by the environment is heritable, so it is not subject to natural selection.”
Answer:
True
Explanation:
Answer from gauth math
The statement "Variation caused by the environment is not heritable, so it is not subject to natural selection" is definitely true. Thus, the correct option for this question is A.
What is Variation?Variation may be defined as the indication of differences in the magnitude of response among individuals in an identical population given an identical dose of a compound.
Some variations are the results of differences provoked by surrounding or environmental factors. Such types of variations are called environmental variations. This type of variation is typically non-heritable in nature.
The variations that locate in the genomic sequence of an individual will tends to cause heritability and can pass from one generation to the next.
Natural selection deals with the process through which populations of living organisms adapt and change accordingly.
Therefore, the correct option for this question is A.

A study showed that the photosynthesis rate of a plant continually increased
over a certain period. Then the rate leveled off. During the study, light inten-
sity and temperature remained constant. The only variable was the concentra-
tion of carbon dioxide surrounding the plant. What was the cause of this
variation in photosynthesis rate?
Plsss helppp
Answer:
The photosynthesis uses carbon dioxide to produces glucose, so the bigger is the concentration, faster the plant will uses it (but that rate have a limit, so it is valid until the limit is achieved, like was explained in the question).
The rate of photosynthesis will increase as you go from low light intensity to high light intensity because there is more light available to power the processes of photosynthesis.
What is the photosynthesis rate of a plant?The higher the concentration, the quicker the plant will utilize the carbon dioxide to make glucose. However, that rate has a limit, therefore it is only effective until that limit is reached.
Because an increase in carbon dioxide results in an increase in photosynthesis, carbon dioxide is the limiting factor at lower concentrations.
Therefore, this indicates that the plant is absorbing more carbon dioxide for photosynthesis, and there is a greater intake of carbon dioxide.

Use the text to identify the sentences with evidence that matches the claim.
Claim 1 --> Tropical rainforests contain more biodiversity than all other biomes.
1) Biodiversity refers to the total number of different species of all kinds living in an area.
2) Tropical rainforests have many of the climate characteristics that organisms of different species need to grow, such as warm temperatures, plenty of rain, and many food sources.
3) There are large amounts of daily sunlight, which provides a great deal of energy to a variety of rainforest organisms.
4) Surprisingly, rain forest soil is very poor.
5) Due to the large amounts of rainfall, nutrients are leached out of the soil quickly.
6) Warm temperatures cause dead organisms to decay quickly, and the nutrients are then used by many different plants.
