Using the explicit formula, calculate how far the students will be swimming on week 10 using Ernest's schedule.

ivann1987 [24]

Ernest would be swimming at 3.25 units on week 10

The explicit formula is given as:

$a_n = a_1 + (n - 1) \times d$

Also, we have the following parameters

$a_1 =1.0$ -- the initial distance

$d =0.25$ --- the difference between concurrent distances

In week 10, the value of n is 10.

Next, substitute 10 for n in the explicit formula $a_n = a_1 + (n - 1) \times d$

So, we have:

$a_{10} = 1.0 + (10 - 1) \times 0.25$

Subtract 1 from 10

$a_{10} = 1.0 + 9 \times 0.25$

Multiply 9 by 0.25

$a_{10} = 1.0 + 2.25$

Add 1.0 and 2.25

$a_{10} = 3.25$

Hence, Ernest would be swimming at 3.25 units on week 10

Why do fluctuations in abiotic cycles have an impact on living organisms and on ecosystems as a whole?

Greeley [361]

<u>Answer:</u>

The fluctuations that are present in abiotic cycles have an impact on living organisms and on ecosystems as a whole because any system that is present in a community requires the support of abiotic system

The materials that are present in an environment require the involvement of both biotic and abiotic system. The biotic community comprises of the living organisms that coexists in an ecosystem whereas abiotic factors are the non-living factors that influences the living of organisms in an ecosystem.

Black fur (B) in guinea pigs is dominant over white fur (b). What is the probability of finding homozygous black offspring in a

Svet_ta [14]

Answer: 100%

Explanation: If both guinea pigs are BB dominant, that means they don't have the recessive trait, so therefore no heterozygous guinea pigs will be created. This leaves 100% homozygous offspring.

Blue jays and crows eat caterpillars and mice. if the number of blue jays increases, what are the two likely effects on other po

suter [353]

If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.

<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>

An organism that preys on other species in order to consume them as food is referred to as a predator.
Prey is a term used to describe an organism that a predator kills.
An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.

Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.

Which statement regarding hemodialysis is true?

SOVA2 [1]

Answer: B. The blood is circulated out of the body for cleansing and then returned.

Explanation:

Hemodialysis is a medical therapy in which the patient's blood is taken out with the help of tubes and treated out of the body. The blood is pumped out using the blood compartment. The blood is circulated using a external filter, that is called as dialyzer. The blood get cleansed and impurities are removed and purified blood returned via circuit back to the body. This technique is used to control the blood pressure and balance of important minerals in the body that involves the potassium, sodium and calcium in the blood.

Based on the above information, option. B is the correct option.
