What kinds of living and nonliving things do you think a marine biologist studies?

Answers

Answer 1

Answer:

Answer:

Marine biology is the study of organisms that lives in the marine environment, the environment that found in sea and oceans. They also study the interaction between these organisms and their environment.

Marine biologists study both living and non-living things in their surroundings where they do research. The living things they study are marine organisms like fishes, sharks, whales, crustaceans, deep-sea organisms, sea plants, microbes and many more living creatures present in the marine environment.

They study their behavior, feeding habits, interaction with other organisms, their role in the ecosystem, mating behavior, etc.

The non-living things a marine biologist study are physical and chemical environment of marine habitat, geology of the area, concentration of salt, and other molecules that affect marine biology.

In both American cotton (Gossypium hirsutum) and Egyptian cotton (G. barbadense) petal spot is a dominant character over no petal spot. When the cross is made within the species, the F2 progeny segregates in a 3:1 ratio with petal spot character in 75% of the population. However, no clear cut ratio is obtained in respect of the same flower character, when the cross is made reciprocally between the above two species. What is the explanation of this fact?

Pathogens can be transmitted through contact with surfaces like doorknobs and countertops.a. True
b. False

Answers

The answer is a. True.

Some pathogens can be transmitted through direct contact with infected person, and some pathogens can be spread through contact with surfaces like doorknobs and countertops. For example, an infected person can touch these surfaces and leave behind pathogens. When an uninfected person touches the surfaces and then touches its skin, the pathogens are transmitted to that person. Staphylococci are the commonly transmitted this way.

a. True
b. False

Answers

The statement 'The leaf-cutter ants do not feed on leaves' is a. True. The leaf-cutter ants on leaf sap. They live in mutualism with fungi they cultivate. The adult ants use fungi to feed the ant larvae. But, to help fungi to survive, they feed them with the leaves after they chew all the pulp from the leaves.

Some animals, such as cows, normally produce only one offspring from each mating. If a cow showed a dominant phenotype, why would a typical testcross be a difficult way to determine the genotype of that animal?

Answers

Answer:

Because of insufficient number of offsprings to determine the result of test cross.

Explanation:

Normally, in genetics, a test cross is a cross between a dominant phenotype (genotype unknown) and a homozygous recessive genotype in order to determine the genotype of that dominant organism.

The result of the test cross is obtained when a 1:1 phenotypic ratio is produced for each trait i.e. 1 dominant trait: 1 recessive trait showing that the parent is heterozygous while all the offsprings will show dominant traits if the dominant phenotype was homozygous. Hence, more than one offspring is required to be able to conclude

In this question, the cow only produce one offspring which may be DOMINANT for the observed trait making it difficult to know if other offsprings will all be dominant or some of them recessive. Hence, it is not a sufficient number needed to determine the genotype from the phenotypic ratio of offsprings.

Celia is staring at the clock waiting for school to end so that she can go to track practice. She notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.Part 1: How many radians does the minute hand move from 1:25 to 1:50? (Hint: Find the number of degrees per minute first.)

Answers

Answer:

The minute hand moves $(5\pi)/(6)$ radians.

Step by step explanation:

We know that measure of complete circle is 360 degrees.

In a clock a complete circle means 60 minutes.

$60\text{ min }=360^(\circ)$

$1\text{ min }=(360)/(60)=6^(\circ)$

The minute hand move from 1:25 to 1:50, it means the minute have cover 25 minutes.

$25\text{ min }=(6* 25)^(\circ)$

$25\text{ min }=150^(\circ)$

Therefore minute hand moves 150 degree.

Multiply $(\pi)/(180)$ to convert degree into radian.

$150* (\pi)/(180)=(5\pi)/(6)$

Therefore the minute hand moves $(5\pi)/(6)$ radians.

How many radians does the minute hand move from 1:25 to 1:50?

Calculations are done as follows:

360 ° /60 minutes = 6° per minute
1:25 to 1:50 = 25 minutes

25 minutes x 6° per minute = 150°
150° (π/180) = 5π/6
