Explanation:
A food chain has four trophic levels. The fourth level has 10 hawks that are a natural predator to the snakes in the ecosystem. How much energy would be available in the first trophic level?
A.
1000
B.
100
C.
1
D.
10,000
Starting with 10 hawks at the fourth level, considering a 90% energy loss per level, we calculate 10,000 units at the first trophic level.
The energy available at each trophic level typically decreases by about 90% due to energy loss through metabolism, growth, and waste production. Starting with the energy available to the hawks at the fourth trophic level, we can estimate the energy at the first trophic level as follows:
Energy at 4th level = 10 hawks
Energy at 3rd level = 10 hawks / 0.1 = 100
Energy at 2nd level = 100 / 0.1 = 1000
Energy at 1st level = 1000 / 0.1 = 10,000
So, the correct answer is:
D. 10,000

For plant stem length, the dominant allele for height is T and the recessive allele is t. If a heterozygous parent for tall stem length crossed with a homozygous recessive parent for short stem length, what would be the phenotypes of the offspring? Include the probability percentages or fractions in your answer.
For a plant stem and a domain allele, the height is set to T and the excessive allele is t. If the tall plant is means that the allele for T and t is 50% short and 50% small.
Hence the offspring would be the short stem.
The hetero parent for the tall (Tt) is crossed with a parent recessive (tt) The percentages are 25% for the tall stem and the 75% chance for a short stem plant.Learn more about the For plant stem length.

The model above shows a cell moving a substance into the cell using a protein to facilitate the transport. Which
substance is most likely being transported through the membrane with this method?
A protein is used to facilitate the transport of a substance into a cell, and the substance is most likely transported through the membrane using this method of facilitated diffusion.
What is facilitated diffusion and what is its significance?Facilitated diffusion is a type of passive diffusion in which the energy of the ATP is not used for the transport of the molecules from the outside to the inside, but there is a protein present on the cell surface that helps the movement of the molecule, and as this protein facilitates the movement, it is called "facilitated diffusion."
Hence, a protein is used to facilitate the transport of a substance into a cell, and the substance is most likely transported through the membrane using this method of facilitated diffusion.

A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimated population of 11,500 individuals on a wildlife preserve of 115 hectares. (One hectare is equal to 2.47 acres of land.) The scientist calculates the carrying capacity at 14,600 individuals.
Part A
Factoring a death rate from natural causes and predation, the beetle population increases approximately 5% each year. Use the Table button to create a table showing the estimated population for each year, starting with the current population and stopping when you’ve reached or exceeded the carrying capacity.
Answer/Explanation:
Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:
Year Calculation Est. Population
1st yr (current yr) 11,500
2nd yr 11,500*105% 12,075
3rd yr 12,075*105% 12,679
4th yr 12,679*105% 13,313
5th yr 13,313*105% 13,979
6th yr 13,979*105% 14,678
The above is how the table would like showing the estimated population for each year.
Answer:
To find the population of beetles each year, we multiply the previous year’s population by 105% (100% + 5%).
Year Population
1 11,500
2 12,075
3 12,679
4 13,313
5 13,978

What is the definition of photosynthesis
Answer:the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Explanation:
What would happen to the cell or organism if the protein is changed as a result of the mRNA being produced incorrectly?
A. The cell or organism will definitely have changes
B.The cell or organism may or may not have any noticeable changes
C.The cell or organisms life expectancy will drastically decrease
D.The cell or organism will not have any changes
Answer:
B. The cell or organism may or may not have any noticeable changes.
Explanation:
Some mutations can cause small changes, if any, such as different colored hair, or they can cause massive changes such as uncontrollable cell division, AKA cancer. Mutations are random so nothing is definite.
The mutation is the alteration in the nucleotide sequence or the proteins. If mRNA is incorrectly produced and alters the protein then there may be or may not be any noticeable changes. Thus, option B is correct.
What is mutation?The mutation is the state in which the bases or the amino acids coding the proteins during the mRNA translation are altered due to mutagens, genetic error, etc.
The mutation in the protein may or may not cause any change as some changes are not noticeable and very small, while some alterations may be big and dangerous.
Therefore, the mutation in the proteins may or may not be noticeable.

What type of offspring are produced by asexual reproduction? *
Answer:
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. This type of reproduction occurs in prokaryotic microorganisms (bacteria) and in some eukaryotic single-celled and multi-celled organisms.
Asexual reproduction produces offspring that are genetically identical to the sole parent, resulting in clones. Such reproduction is found in various species and can occur via methods like binary fission, fragmentation, budding, and parthenogenesis. Although this allows for quick population growth in stable environments, it limits genetic diversity.
Explanation:Asexual reproduction results in offspring that are genetically identical to the single parent and to each other. This means the resulting offspring are clones of the original parent. Different methods of asexual reproduction include binary fission, fragmentation, budding, and parthenogenesis, which vary among species but share the commonality of not requiring the genetic exchange that occurs in sexual reproduction. While this type of reproduction can be advantageous in stable environments where rapid population growth is beneficial, it lacks genetic diversity, which can be problematic when adapting to changing environments or resisting diseases.
Examples of organisms that reproduce asexually include bacteria that utilize binary fission, sea stars, and sea anemones that can regenerate from fragments, and some plants that can produce genetically identical offspring through budding or fragmentation.

Answer:
C) pioneer species
Explanation:
Rebekah is most likely researching pioneer species that are in option C, as lichens are known to be some of the first organisms to colonize barren or disturbed habitats, such as newly formed lava fields, and are therefore considered pioneer species.
What is the pioneer species?
Pioneer species are the first species to colonize a barren or disturbed habitat, such as a newly formed lava field, a recently retreating glacier, or an abandoned building. These species are able to grow in harsh conditions and are often characterized by rapid growth rates, high reproductive rates, and the ability to fix nitrogen. Pioneer species can be plants, lichens, or even bacteria, and they play an important role in the process of primary succession. Pioneer species are able to grow in these harsh conditions because they have adaptations that allow them to obtain nutrients and water from their environment.
