What does "fishing down the food web" mean?
Answer:
Fishing down the food web is the process whereby fisheries in a given ecosystem, "having depleted the large predatory fish on top of the food web, turn to increasingly smaller species, finally ending up with previously spurned small fish and invertebrates".
As a genetic counselor, you advise couples about the possibility of genetic disease in their offspring. This morning you met with an engaged couple, both of whom are phenotypically normal. The man, however, has a brother who died of Duchenne-type muscular dystrophy, an X-linked condition that results in death before the age of 20. The allele responsible for this disease is recessive. His fiancee, whose family has no history of the disease, is worried that the couple's sons or daughters might be afflicted.
Requied:
a. How would you advise this couple?
b. The sister of this man is planning to marry his fiancée's brother. How would you advise this second couple?
Answer:
a. This couple should not worry.
b. This couple should worry.
Explanation:
a. The man should not be worried. This is because he is normal (phenotypically).
b. They should be worried because the sister of the man can be a carrier of the recessive allele. If she was a carrier, then half of their male children can be affected.

Answer:
The difference between ethical, and finally scientific questions, are based upon their root word. Such as an ethical question may involve race and heritage, while a legal question may involve anything that involves the law such as court questions and can be resolved by the judge not the jury. Finally scientific questions can involve a question thats mainly based around science such as items that you can test or measure.

Two plants are crossed, and the traits of height and color are assessed in the offspring. The following cross was conducted: TTPP x ttpp. Which of the
following choices correctly describes the offspring?
T = dominant allele for height, tall plant
t = recessive allele for height, short plant
P = dominant allele for color, purple
p = recessive allele for color, white
TP

O All are tall and purple
O Three-quarters of the plants are short and white
All are short and white
Three-quarters of the plants are tall and purple
Answer:
A. All are tall and purple
Explanation:
When you set up a punnet square, all of the results would be TtPp.
When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).
So to break it down:
Tt -> tall plant
Pp -> purple plant
so they are all tall and purple.

A scientist exploring in the rainforest found an unclassified organism. It is multicellular and made of multiple thread-like structures. The organism has cells with a nucleus and a cell wall made of chitin. The scientist should classify this organism as belonging to the kingdom—
Answer:
Kingdom Fungi
Explanation:
Based on certain characteristics possessed by living organisms, they have been classified into five different kingdoms namely; plantae, animalia, monera, protista and fungi. Organisms with similar characteristics have been placed under the same kingdom.
Kingdom Fungi is a kingdom that contains organisms that possess characteristics different from plants and animals. Some of these features are those possessed by the unclassified organism found in the rainforest and they are as follows:
- They are eukaryotic (possess a true nucleus) and multicellular (have more than one cell).
- Their cell wall is made of chitin (a carbohydrate)
- They are made of multiple thread-like structures called HYPHAE.
Based on these mentioned characteristics above, the scientist should classify this organism as belonging to the kingdom FUNGI.
What is Nuclear Transplantation?
Answer: Nuclear transfer is a form of cloning. The steps involve removing the DNA from an oocyte, and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining in a pluripotent state.Nuclear transfer is a form of cloning.

Explanation:
The functions of two physical structures of plants are described below:
Structure 1: Holds the leaves of the plant toward the light.
Structure 2: Helps reduce water loss.
What statement is true about the functions?
Structure 1 is the stamen and Structure 2 is the pistil.
Structure 1 is the stem and Structure is the waxy covering.
Structure 1 is the pistil and Structure 2 is the fuzzy hair.
Structure 1 is the waxy covering and Structure 2 is the stamen.
Answer:
b
Explanation:
the structure will continuously move and compete for sunlight
the wax is so that the moisture has to go thought it and will either be part of the wax or be absorbed back into the plant
The statement which is true about the functions is structure 1 is the stem and structure 2 is the waxy covering with respect to their functions.
What do you mean by Water loss?Water loss in plants may be defined as the process of evaporation of water to the atmosphere from the leaves of a plant in the form of water vapor.
The stem is the part of the plant that holds the leaves of the plant toward the source of light. While the waxy covering is responsible for the process of transpiration in the plants.
Therefore, the statement which is true about the functions is structure 1 is the stem and structure is the waxy covering.

By the end of the Jurassic Period, the Sundance Sea was filled up with sediments and formed a swampy lowland known as
Morrison Foredeep
Panthalassa Moor
Franciscan Terrane
Great Black Swamp
Solenhofen Swamp
Answer:
Morrison Foredeep
Explanation:
Morrison Foredeep is a swampy lowland formed due to filling of Sundance Sea with sediments during Jurassic period. Series of sedimentary rocks deposited during the Jurassic Period in the western North America, from Montana to New Mexico. Morrison Formation is famous for the presence of dinosaur fossils, which have been collected since 1877 about more than a century ago beginning with a find near the town of Morrison, Colorado.
True or False: The larval stage of the sea urchin is called the pluteus.
Answer:
False
Explanation:
it is called planktotrophs.
Answer:
larva, which is called a pluteus, has a small, wartlike bud that grows into the adult while the pluteus tissue disintegrates. In both examples it is as if the organism has two life histories, one built on the ruins of another.

In how many revolutions can a bicycle
wheel of diameter 4.9 m cover a dis-
tance of 46.2 km?
Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

Answer:
living
Explanation:
Biotic factors are the living parts of an ecosystem. Because of the way ecosystems work – as complex systems of competition and cooperation, where the action of every life form can effect all the others – any living thing within an ecosystem can be considered a biotic factor. Biotic factors such as soil bacteria, plant life, top predators, and polluters can all profoundly shape which organisms can live in an ecosystems and what survival strategies they use.
