A scientist was observing a population of sea cucumbers in coastal waters. Over a 10-day period, she collected the following inf

ormation about the distribution of the individuals within a 10-meter square plot:
Distribution of Sea Cucumbers within a 10-Meter Square Plot

Time of Day

Use the data above as a basis as you answer the following questions: (10 points)

(a) Identify THREE biotic or abiotic factors that could cause the sea cucumbers to vary their distance from each other throughout the day.

(b) Using one of the factors listed in part (a) as an independent variable, write a hypothesis that proposes how this variable could cause the sea cucumbers to vary their distance from each other.

(c) Design a procedure for a controlled experiment to test your hypothesis.

(d) Describe the results that would support your proposed hypothesis and the results that would refute your hypothesis.

The flu vaccine (administered as a shot or a nasal spray) is made of a combination of the different types of influenza viruses t
Marat540 [252]

Answer:

This happens because viruses mutate and vary according to the environment they face. That is why different strains occur and appear every day, which must be updated in the vaccines, in order to have immunity up to date and keep up with the viral mutation without making us sick.

Explanation:

Viruses are acellular structures that do not have their own metabolism or replication method, it is because they must dominate and invade the human body so that its DNA or RNA is coupled to the human and this uses the human machinery to be able to replicate.

On the other hand, as infections occur and viruses appear, they can associate with bacteria forming bacteriophages, they can mutate within an organism that is infected by more than one viral infection and they can even adopt retrovirus mechanisms, which day by day. These new viruses are called as new strains, which evolve and will have to be coupled with vaccines.

Vaccines are a method of natural ACTIVE immunity, that is, part of the virus is inoculated, so that it generates the formation of a specific antibody in the body.

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter
Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

As a mechanism of evolution, natural selection can be most closely equated with __________.
olga_2 [115]
As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.

Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.
