Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
Explanation:
A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

5. What types of genes change very slowly?
Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

What is secondary succession
An example of Secondary Succession by stages:
1. An area of growth.
2. A disturbance, such as a fire, starts.
3. The fire destroys the vegetation.
4. The fire leaves behind empty, but not destroyed soil.
5. Grasses and other herbaceous plants grow back first.
6. Small bushes and trees begin to colonize the public area.
7. Fast-growing evergreen trees and bamboo trees develop to their fullest, while shade-tolerant trees develop in the understory.
8. The short-lived and shade-intolerant evergreen trees die as the larger deciduous trees overtop them. The ecosystem is now back to a similar state to where it began. good day

Explanation:
Xylem is responsible for the transportation of mineral and water from Roots to the rest of the plantby diffusion and suction caused due to transpiration.
Meteorologists often try to predict what the high temperature of a day will be several days beforehand. Why do meteorologists not try to predict the high temperature of a day six months in the future?
A. Weather does not follow any predictable patterns.
B. Meteorologists have this information but choose not to share it with the public.
C. It is impossible to know what season it will be six months in the future.
D. Weather is a highly complicated system that is very difficult to predict.
HELP
Answer:
Its D- Weather is a highly complicated system that is very difficult to predict.
Explanation:
Weather has a pattern so A is not the answer and no way Meteorologists would keep information to themselves so not B and lastly it's not impossible but just very hard so C is out, which leaves D.

What factors influence ocean water density?
Answer:
Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in, the higher the density. Density can be calculated by dividing an object's mass by its volume.
Explanation:
Many snakes and lizards live in the desert, where temperatures are high during the day and cold at night. How does the temperature range affect the size of the snakes and lizards?
A. High daytime temperatures allow them to grow as large as the food supply will allow.
B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.
C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.
D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.
Answer:
A. High daytime temperatures allow them to grow as large as the food supply will allow.
Explanation:
Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.
Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.
If 575,250 calories of energy are available at the first trophic level, calculate the number of calories available to the 2, 3 and the 4 level
Answer: See explanation
Explanation:
The trophic level of an organism simply refers to the position that is occupied by an organism in a food web. It should be noted that in the next trophic level, only 10% of the energy will be available. Therefore,
1st trophic level = 575,250 calories of energy.
2nd trophic level = 575,250 × 10% = 57525 Calories of energy.
3rd trophic level = 57525 × 10% = 5752.50 Calories of energy
4th trophic level = 5752.50 × 10% = 575.25 Calories of energy

Why are data tables and graphs essential in scientific reporting?
A. They shorten scientific reports considerably.
B. They are accessible to people who cannot read.
C. They make scientific reports more interesting to read.
D. They compare data in a clear and concise way.
Answer:
c
Explanation:
Since most of the data scientist collect is quantitative, data tables and charts are usually used to organize the information • Graphs are created from data tables • They allow the investigator to get a visual image of the observations, which simplifies interpretation and draw
How would you calculate the distance of a paper airplane
Answer: uh Well, Your foot should be at the end of the starting line you prepared earlier. Once you're ready, you can throw your plane. Measure the distance the paper plane traveled (in centimeters or meters) from the starting point with the tape measure. Your lab notebook should include this data in a table. "Plane 1" will take off from this point.
Explanation:
Read above-
Case Study The Selkirk Rex cat is a breed known for its curly hair. The allele responsible for this curly hair exhibits incomplete dominance. Two copies of the allele yields very curly hair, a slender body, and large ears. One copy of the allele yields a more sturdy body, wavy hair, and smaller ears. Cats with one copy are preferred for professional cat shows. A man from Argentina recently inherited two sister Selkirk Rex cats from a relative and is interested in breeding them to produce more curly-haired cats. One cat carries two copies of the Selkirk allele. The other Selkirk Rex cat carries one Selkirk allele. What genotypes should he seek in mating partners for his cats to produce the most heterozygous kittens possible in the next generation? Note: he doesn't want any kittens that do not have wavy or curly hair. What genotypes should the breeder choose for mates for his Selkirk cats? Choose the beſt answer from the choices below to maximize the number of heterozygous kittens AND maintain the mutation in the population for future breeding. For the SS cat, he should choose Ss. For the Ss cat, he should choose 55. For the SS cat, he should choose ss. For the Ss cat, he should choose Ss. For the SS cat, he should choose 55. For the Ss cat, he should choose Ss. For the SS cat, he should choose ss. For the Ss cat, he should choose SS.

Which best explains what occurred at point X on the curve?
A. The birth rate was equal to the death rate.
B. The death rate was greater than the birth rate.
C.The rate of emigration was equal to the birth rate.
D. The rate of immigration was greater than the death rate.
Answer:
A. The birth rate was equal to the death rate.
Explanation:
The point X is the carrying capacity and this pajae could be ascribed as the plateau stage of population growth, whereby the maximum number of individuals of a particular species which the environment can support has been reached. Hence, giving a long, flat area of the logistic growth curve. At the stage marked x, growth would seize as the population hovers to attain equilibrium with the natality and fatality rate becoming equal, that is birth rate will be equal to the death rate in the population.
