Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems.

Plants and animals are multicellular organisms?
Which statement best describes the difference between them and other organisms?
(A) they have organelles in each cell perform function to keep the cell alive
(B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
(C) the cells that make them up are larger than cells that make up bacteria, yeast, or amoeba
(D) they can all use socialized cells to make their own food by capturing the suns energy, other organisms cannot do this
Answer:
B) they are made of many specialized cells types that perform specific functions to keep the entire organism alive
Explanation:
A multicellular organisms are organisms that possess many cells in its body system. As stated in this question, plants and animals fall under this multicellular category. These cells begin to specialize in function as they divide through a process called CELL DIFFERENTIATION.
In comparison with the number of cells of other organisms, which are unicellular (one cell), multicellular organisms are made of many specialized cells types that perform specific functions to keep the entire organism alive whereas in unicellular organisms, only the organelles in one cell performs the function.
How did economics delay scientists' first attempts for conservation in each story?
The correct answer to this question is the following.
Unfortunately, your question is incomplete. You did not attach the two stories. So we do not know what the topic is. You also forgot to attach a link or the title of these stories.
However, trying to help you we did some deep research and can comment on the following.
There are two stories about Conservation Activity. One is about "Using Forest Wisely" and the other is about "Community Conservation."
If that is the case, we can say that the economics delay scientists' first attempts for conservation affect the conservation study and the environment in that cutting those trees for economic purposes directly impact the wildlife and nature of the region.
Trees are the sentient beings that produce the oxygen human beings need to breathe fresh air. They clean the air because trees "breathe" carbon dioxide. The uncontrolled cutting down of trees could affect because resources could be scarce, increasing prices of goods.
One of the stories refers to the case of gorillas in places such as Rwanda or Uganda, risking the habitat of these animals and the entire environment of those forests, which also results in affecting the economy of the places.

Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw
PW Pw pW pw
PW PPWW PPWw PpWW PpWw
Pw PPWw PPww PpWw Ppww

5. What gametes are produced by the following organisms: a. Genotype YyRr, if Y and R are on different chromosomes b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
a) YR, Yr, yR, yr
b) YR, yr
c) Yr, yR
d) YR, yr, Yr, yR
Explanation:
Before gametes are formed, during anaphase sister chromatids separate and migrate to the poles. Following the low of segregation and independent assortment, alleles from the same trait and from different traits separate independently from each other. During this separation, there might be different gene combinations according to their position in the chromosome, the occurrence of crossing over, and the destiny of each chromatid.
a. Genotype YyRr, if Y and R are on different chromosomes
Genes are located in two different chromosomes, which means that there might be four possible gametes.
YR, Yr, yR, yrb. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YRyrc. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
Genes are located in the same chromosome, which means that there might be two possible gametes.
YryRd. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
The fact that there is 50% crossing over means that these genes are not linked. There are four possible gametes

The parental cross that was most likely responsible for the percentages of offspring fur color, the scientist found, BW x WW. The correct option is A.
What is crossing?The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
Therefore, the correct option is A. BW x WW is the result of the crossing over of offspring for a mated pair of hamsters.

A Class-A 10 mL pipette is supposed to dispense 10.00 mL of water. A lab technician makes three measurements of the volume that the pipette actually dispenses, and obtains volumes of 9.70 mL, 9.69 mL, and 9.71 mL. The pipette is:__________
a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise
Answer:
d) Neither accurate or precise
Explanation:
Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Countercurrent flow met the goals due to difference in concentration gradient.
Explanation:
Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood
In fluid or a flowing body when there is interexchange or a crossover of some fluids with each other is called countercurrent flow while when the fluid flows in the same direction then it is called parallel flow.
Countercurrent meets goals because of concentration gradient differences.
Countercurrent and parallel flow can be explained as:The goals are met in countercurrent because of the opposite direction while in parallel they are not achieved because of the same direction.Countercurrent flow in fishes helps them to increase the blood oxygen level from water as this system help them efficiently maximize the oxygen needed for respiration.If the parallel flow is used then the concentration gradient would be less and hence less oxygen will be available from the water to fishes.Therefore, countercurrent achieves its goal while parallel dies not.
