Answer:
sunlit zone or the euphotic zone
Explanation:
The highest layer of the world's seas is washed in daylight during the daytime. This brilliant sea layer is known as the sunlit zone or the euphotic zone (euphotic signifies "sufficiently bright" in Greek) or the epipelagic zone (epipelagic signifies "upon the ocean")

explain how the structure of a book lung allows it to perform its function
Answer:
Book lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.
A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
Answer and Explanation:
Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.
Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

Answer: dna replication happens in interphase before the mitosis
Explanation: During interphase the cell’s DNA inside the nucleus replicates forming two strands of DNA or chromosomes. In the interphase the DNA replicates in the S phase. Don’t confuse with G1 since in G1, which comes before S phase, replicates the cellular contents needed for this process

B. It will remain the same.
C. it will increase very fast.
D. It will increase slowly.

how does greenhouse effect warm the earth?
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)
Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

25 POINTSSS AND BRAINLY THE SELECTED ANSWER IS WRONG BTW
Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Summarize the benefits and drawbacks of becoming a veterinarian,
Answer:
Drawbacks: Veterinary school is long and extensive, some surgeries can take hours, sometimes you may get an uncooperative animal, you might have to deal with putting an animal down, which can be hard. You also might be scared for live with graphic images, lol.
Benefits: Vets get paid a lot, they help animals, they help animals live the best life, people are VERY appreciative of the work they do for animals, they are always around animals, so they may see the cutest puppies!

Answer:
Cellulose - It is described as a complex carbohydrate that forms the main constituent of the cell wall in most plants and is important in the manufacture of numerous products like pharmaceuticals, textiles, etc.
Chlorophyll - Any of a group of green pigments that are found in the chloroplasts of plants and in other photosynthetic organisms such as cyanobacteria.
Chloroplast - An organelle found in the cells of green plants and in photosynthetic algae, where photosynthesis takes place.
Bryophyte - Any plant of the division Bryophyta, defined "sensu lato" to comprise the mosses, liverworts, and hornworts, and corresponding to all embryophytes that are not vascular plants.
Pterophyte - It is characterized as any fern(seedless plant) that is a division of Pteridophyta.
Gymnosperm - Any plant such as a conifer whose seeds are not enclosed in an ovary or those who don't bear seeds or fruits. Example; Cycads.
Cone - A cone-shaped flower head of various plants like banksias and proteas.
Angiosperm - Any flowering plant characterized by having ovules enclosed in an ovary and thus, produces fruits, as well as, seeds.
Flower - A reproductive structure in angiosperms and often conspicuously colorful and typically including sepals, petals, and either or both stamens and/or a pistil.
Cuticle - A noncellular protective covering outside the many invertebrates and plants.
Vascular tissue - The complex tissues that consist of various cell types and primarily responsible for transporting liquid and other nutrients throughout the plant or animal body.
Xylem - A vascular tissue in the land plants primarily responsible for the distribution of water and minerals that are taken up by the roots and also the key component of the wood.
Phloem - A vascular tissue in land plants primarily responsible for the distribution of sugars and the nutrients manufactured in the shoot.
Roots - The part of the plant which is generally underground that anchors and supports the plant body. It absorbs and stores water and nutrients, and in some plants is able to perform vegetative propagation.
Root hairs - The rhizoid of a vascular plant or a tabular outgrowth of a trichoblast, hair-forming cell on the epidermis of a plant root.
Stems - The above-ground stalk of a vascular plant that supports individual parts of a plant like leaves, flower, fruits, etc.
Leaves - The green and flat organ that represents the most prominent feature of the most vegetative plants.
Photosynthesis - The process by which plants and other photoautotrophs convert light energy into chemical energy. For example; Plants use air, water, along with sunlight to synthesize their food(carbohydrates and waste oxygen).
