A plant that lives in the canopy of the rainforest would not get as much sunlight for photosynthesis.
How will the canopy effect the photosynthesis?The canopy refers to the dense ceiling of trees and their branches, whereas the understory refers to the more widely spaced, smaller tree species and young individuals that form a fragmented layer beneath the canopy.The interior is shielded from the canopy's extremes: temperature swings, harmful sun radiation, and powerful winds. The light is diffused and subdued, the humidity is higher and more consistent, and the lower canopy receives very little direct sunshine.hence the plant under the canopy would not get as much sunlight for photosynthesis.

Answer:
Energy
Explanation:
Hibernation allows an animal to save energy during a time in which there is not a large food source.
This generally occurs to carnivorous as well as omnivores in which their prey is "dead" during the time, or have migrated.
An example of an animal that hibernates during the winter is the Grizzly Bear, who generally eats to full before they hibernate for the winter.

A dam is built that changes water flow nearby. The water flowing through a marsh completely stops. What is the most likely effect of this change?
A. The marsh will become less productive.
B. The marsh will have more oxygen.
C. The marsh will grow more plants.
D. The marsh will have more photosynthesis.
Answer:
A: The marsh will become less productive
Explanation:
Option A is the correct answer because, if the water flow changes to the point where no water is able to enter a certain area, most plant life will die out.
There are a few plants that can survive with very little water, but not enough to sustain a whole ecosystem.
The marsh will not have more oxygen, because underwater plants acquire oxygen through the water surrounding it (oxygen diffuses into the water).
The marsh will not grow more plants, because water is the key factor needed in order for plants to grow, and due to no plants being able to sustain themselves, the rate of photosynthesis will also decrease.

Which statement accurately describes reproduction in animals
All animals can reproduce asexually, and some can reproduce sexually
All animals can reproduce sexually, and some can reproduce asexually
Animals only reproduce sexually
Animals only reproduce asexually.
Answer:
B
Explanation:
it just is trusttttttt
Animals can use both sexual as well asexual means for their reproduction. Some animals reproduce asexually through budding while others can reproduce through both sexual as well as asexual modes. Higher animals reproduce through the sexual mode of reproduction. So the correct answer is Option B.
Which animals reproduce asexually?Oligochaetes, planarians, sea stars, starfish, sharks, Crayfish, wasps, snakes like pythons, etc. are some of the animals that reproduce asexually. In the asexual mode of reproduction fusion of gametes does not occur and there is no change in the number of chromosomes of an individual. The same set of genes is passed on from the parent to the offspring and the newly formed offspring is an identical copy of its parent.
Some animals show an alteration between the sexual and asexual modes of reproduction. This is known as heterogamy. Examples of heterogamy include insects and rotifer.

Illegal fishing is thought to account for what percent of fish caught?
A. 10-20
B. 15-40
C. 20-50
D. 50-70
Thank you!
Illegal fishing accounts for a substantial portion of global fish catches, likely falling within the range of 15-40% based on studies and reports on under-reporting and the proportion of illegally caught seafood entering the United States.
Illegal fishing is a significant problem that affects marine ecosystems and economies around the world. According to research, the percentage of fish caught through illegal, unreported, and undocumented (IUU) fishing is substantial, contributing to over-exploitation and depletion of fish stocks. Considering the report by Agnew et al. in 2009 and the data on the under-reporting of global marine fish catches, it is reasonable to deduce that the percentage of fish caught through illegal means could be on the higher end of the provided options.
Additionally, taking into account that 25-30% of wild-caught seafood imported into the United States is illegally caught, as stated by Pramod et al. in 2014, and the significant under-reporting by as much as 50%, the range of illegal catch is likely considerable. Hence, the answer to the question of what percent of fish caught are due to illegal fishing is option B. 15-40%.

how can mutation in a gene lead to a new trait in an organism ?
Answer: D. The mutated gene codes for a protein that causes a new trait
Explanation:
A mutation is a change in the DNA sequence that can occur from multiple causes. For example, by errors during replication or by the action of mutagens such as UV radiation, among others. When a mutation occurs, if not repaired, it can lead to the production of a different protein. This is because genes code for amino acids, which bonded together form proteins. A change in a DNA gene base can lead to code for a different amino acid (or even adding a new one or causing another to be lost). This alteration can lead to the synthesis of another protein involved in the expression of a trait, and giving rise to a different characteristic, which can be beneficial or harmful.

The four main spheres of the exterior of Earth are the _____. atmosphere, cryosphere, hydrosphere, and lithosphere anthrosphere, atmosphere, cryosphere, and biosphere atmosphere, lithosphere, biosphere, and hydrosphere atmosphere, lithosphere, biosphere, and gemosphere
Answer: lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
Explanation: Hope this helps!!!
The correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.
Explanation
Earth is a planet that belongs to the solar system. The earth is composed of several elements that constantly interact forming a system, that is to say, it is composed of interrelated and dependent parts, so if one of the parts changes, the others are modified, altering the entire system. The main parts of the Earth are its subsystems that are the lithosphere, the atmosphere, and the hydrosphere. These subsystems fulfill specific functions that allow the development of life on Earth. These subsystems are related. Each system has a particular function, the atmosphere contains oxygen and carbon dioxide; the hydrosphere contains all forms of water on earth, and the lithosphere is made up of mineral salts and support for living things. At the same time, these three subsystems allow the existence of the biosphere, that is, the subsystem referring to all forms of life on Earth. So, the correct answer is C. Atmosphere, lithosphere, biosphere, and hydrosphere.

Where do electrons get their energy in photosystem I?
A. From NAD and NADPH
B. From energy in photons
C. From ADP and ATP
D. From glucose in the Calvin cycle
When chlorophyll or carotenoid molecules absorb light and enter a photoexcited state, electrons in Photosystem I acquire energy, hence option b is correct.
What is the light reaction?Through an electron transport chain, the excited chlorophyll electrons are moved from photosystem II's electron acceptors to photosystem I.
Two photosystems—Photosystem II and Photosystem I—are present in photosynthetic eukaryotes and cyanobacteria.
An electron is excited and lost from a PSII reaction center in chlorophyll as a result of light energy (P680).
Therefore, Photosystem I uses light energy to move electrons from ferredoxin on the stromal side of the thylakoid membrane to plastocyanin on the lumenal side of the membrane, hence option b is correct.

A. Chains of DNA codons and RNA anti codons form.
B. Specific codons pair with specific anti codons.
C. DNA strands form a backbone of sugar rings and phosphate groups.
D. Peptides bond to nucleic acid molecules.
Answer:
B. Specific codons pair with specific anti codons.
Explanation:
The nucleotide sequence of mRNA serves as a template for protein synthesis. During the process of protein synthesis, the mRNA nucleotide sequence is read in the form of triplet codons. The tRNA with the complementary anticodon sequence joins the mRNA.
There is base pairing between codon of mRNA and its complementary anticodon of tRNA followed by the formation of a peptide bond between existing amino acid on the ribosome and incoming amino acid carried by tRNA.

It would be extremely rare for the freckled parents to have a child without freckles because freckles are dominant.
b
The parents will most likely have three children with freckles before having a child without freckles.
c
Every time they reproduce, the parents have a one in four chance of having a child without freckles.
d
If the parents already have three children with freckles, then they are more likely to have a child without freckles.
Answer:
It might be C but sorry if I'm wrong
Two heterozygous parents for the dominant freckle trait (Ff) have a one in four chance of having a child with no freckles (ff) using a Punnett square to determine the probabilities.
Explanation:When considering whether two heterozygous parents can have a child with no freckles, we utilize a Punnett square to determine the possible genetic outcomes. Since freckles (F) are dominant over no freckles (f), a heterozygous individual will have one of each allele (Ff). When these parents have children, each parent has a 50% chance of passing on either the F or f allele.
Using a Punnett square to illustrate this, we would see that there are four possible genetic combinations for their child:
FF - Child with frecklesFf - Child with freckles (heterozygous like the parents)fF - Child with freckles (heterozygous like the parents)ff - Child with no frecklesThus, the correct answer is that every time they reproduce, the parents have a one in four chance of having a child without freckles (option c). This is because the chance for each genotype (FF, Ff, fF, or ff) is equal when both parents are heterozygous (Ff).
