Pesticides often do not just kill the target pest but also poison
inects in and
around the fields. These insects with the pesticides can be eaten by other animals and poison them.
Some pesticides are suspected of disrupting the
of wildlife and people. These
chemicals
because they are fat soluble and get passed up the food chain
by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:
Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.
Answer:
If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.
Explanation:
Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.
The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.
When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:
Dominant RecessiveWhen one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.
Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.
Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.

What are 4 different protists and what makes them special
Answer:
Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Explanation:
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.

Recently, a type of genetically modified fish has
been approved for sale for human consumption.
The modified fish contain a growth hormone
gene from a different fish species. As a result, the
modified fish grow rapidly and are ready to sell in
almost half the time it normally would take. The
modified fish are able to produce the new growth
hormone because
(1) each of their cells contains the new gene to
produce growth hormone
(2) each gene contains the code to synthesize
carbohydrates
(3) the altered gene directs the mitochondria to
synthesize the hormone

They are able to face problems, avoid any distractions, and they can also politely proceed forward. Adaptable people also have the ability to think ahead and focus consistently on their improvement.
They have a balance of thoughts like, what can be done better for personal improvement. Adaptable people always focus on both the risks and the rewards.
They do not see their mistakes or failure, but they try to see opportunities. Adaptable people also don’t have a fixed solution to use every time. They think of a wide variety of ideas and resources that they can take from. Because of this, they are also more likely to think of new things in real time
Therefore the correct option is C.

are sea urchins so important in the estuary? What would happen if they were to die off?
Can someone do this quick?
Answer: A.
Explanation:
Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.
Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.
The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

Can someone please give a small description on these words based off of animals cell
Golgi body
Cell membrane
Centrosome
Nucleus
Vacuole
Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

In medicine and veterinary medicine, saline solutions are compared with the normal concentration of
sodium (~143 mmol/L) in healthy blood. Three saline solutions are available: isotonic, hypotonic, and
hypertonic.

Interpret each as higher, lower, or equal to
normal blood Nat concentration.

Hypertonic Saline
Answer: isotonic saline is equal
Hypotonic saline is lower
Hypertonic saline is higher
Explanation:
Here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.
What is the significance of the saline solution in the medications?It is critical in the medication because the solution is made up of a mixture of salt and water through which the drugs are delivered and because it is given in intravenous (IV) therapy or to rehydrate patients when there is a need for it. The saline concentration should be regulated here in this solution, or else it may change the blood cells' structure.
Hence, here, three saline solutions are available: the isotonic saline solution has an equal sodium concentration, the hypotonic solution has a lesser sodium concentration, and the hypertonic solution has a high sodium concentration.
