Healthy ecosystems depend on a variety of factors working together in balance.

Some key factors include:

1. Biodiversity: Healthy ecosystems have a rich variety of species, including plants, animals, and microorganisms.

2. Nutrient Cycling: Ecosystems rely on the cycling of nutrients, such as carbon, nitrogen, and phosphorus, to support the growth and survival of organisms.

3. Energy Flow: Ecosystems depend on the flow of energy from the sun. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis.

4. Interactions and Relationships: Healthy ecosystems are characterized by complex interactions and relationships among organisms.

A scientist observes a geyser erupting. Which two objects must be interacting beneath the surface?
O well and spring
O spring and magma
O magma and groundwater
O groundwater and unsaturated zone

Answers

Answer:

c

Explanation:

Magma and groundwater are responsible for the eruption of geyser.

Geyser

Geyser eruptions are as a result of the conversion of thermal to kinetic energy during decompression.

When the groundwater deep in the ground is heated up by magma, pressure is released and the water will erupt out of the ground as a geyser. Eruptions occur about every 50-100 minutes.

D) Environmental change 1 is reduced space and environmental change 2 is lack of food.

Answers

Answer: I would say answer C

Explanation:

The statement which is true about these environmental changes is that the Environmental change 1 is reduced space and environmental change 2 is disease. Thus, the correct option will be C.

What is Environmental change?

Environmental change can be defined as a change or any disturbance of the environment which is most often caused by human influences and the natural ecological processes. Environmental changes are the effect of changes which include various factors, such as natural disasters, human interferences, or the animal interaction.

The statement which is true about these environmental changes is that the Environmental change 1 is reduced space and environmental change 2 is disease. This is because, in environmental change 1 the different species compete for resources and in environmental change 2 the species are affected with infectious virus.

Therefore, the correct option will be C.

You are a genetic counselor. A couple comes to you for advice. The female is eight weeks pregnant with their first child. Both are Ashkenazi Jews, a segment of the population in which Gaucher disease is relatively common. Gaucher disease is a condition that can range from mild and treatable symptoms to severe, debilitating problems. The disease is an autosomal recessive pattern. Which of the following statements is true?

The child will likely have Gaucher disease if she has inherited recessive alleles from each parent.
The child will likely have Gaucher disease if she has inherited one dominant allele from her father.
The child will only have Gaucher disease if she has inherited both dominant alleles from her parents.
The child will only have Gaucher disease if she has received one recessive allele from her mother.

Answers

A) The child will likely have Gaucher Disease if she inherited RECESSIVE alleles from each parent.

D is ruled out because if the child only received one recessive allele but her other allele is dominant, then the most she could be is a carrier. Dominant over recessive.

C is wrong because the question states that the disease is a recessive pattern, while C is stating that the child would only have it if it inherited dominant alleles.

B is wrong. Like D, it’s dominant over recessive and the most the child could be is a carrier.

Therefore, I believe the answer is A, the first one.

can someone answer this pls??

Answers

Answer:

75% brown, 25% white

Explanation:

This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).

According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.

Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:

¾ or 75% brown and ¼ or 25% white

Choose all the answers that apply. The atmosphere: is mostly made of nitrogen is weightless protects earth from harmful radiation contains water vapor is affected by events in the hydrosphere

Answers

Answer:

The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.

Explanation:

The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.

The Earth´s atmosphere is composed of water vapor, N₂ (78.08%), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. Water vapor might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. They protect the Earth from harmful radiation.

The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.

Answer:

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.

Answers

Answer:

Both creates new cells

Explanation:

Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.

What is meiosis?

Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.

In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.

Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.
