A) 150 UNITS TO THE LEFT

^ answer

Explanation :

I believe this is the answer since there’s force on the left which is 450 ( a negative 450) and a force on the right 300 ( a positive 300) so overall there’s more force on the left side ( by 150) and you’ll need 150 units to the right to make it balanced or equilibrium.

Answer:

The answer is 150 units to the left.

Explanation:

You start with the bigger number and subtract it because they ´re going opposite directions. It goes to the left because your net force will go in that same direction with the bigger number.

450 - 300 = 150 units to the left

I hope this helps u! :D

How do you think water and carbon dioxide<br> used for photosynthesis get into the plant's leaf?
Leto [7]

Answer:

The leaves of plants contain openings called stomata, which are used for the exchange of gases. Carbon dioxide, combined with water in photosynthesis, is drawn in through the stomata. Oxygen, a byproduct of the process, is released through these openings, along with water vapor in a process called transpiration.

Explanation:

Hope this helps! :)

How does biomass in a community change as succession proceeds?
fenix001 [56]

A

It increases because the biodiversity of the community in the environment during succession increases.

Explanation:

During primary succession, the nutrients in the rocks are gradually released as pioneer plants help break up the rocks into soil. These nutrients are taken up and more species of plants are able to thrive in the environment including the perennial and biennial plants. These plants provide food and shelter for higher organisms (hence many longer food webs and chains) and this is why biodiversity increases with increased succession until the climax community is reached. Increased biodiversity means increased biomass.

A student proposes that left-handedness is a recessive trait and is hidden in much of the human population. a survey of his clas
djverab [1.8K]

The frequency of the recessive allele for the left handle will be in this case equal to q^2 = 0.25 >> q = 0.5.

<h3>What is the Hardy Weinberg principle?</h3>

The Hardy Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies.

The Hardy Weinberg principle states that the sum of the dominant allele and the recessive allele in a population is equal to 1 (p + q = 1).

This principle also states p2 + q2 + 2pq = 1, where p^2 is the dominant homo-zygous allele, 2pq the heterozygous frequency and  q^2 the recessive homo-zygous frequency.

In this case, 9 individuals represent 25% (q^2 = 0.25), thereby the feecuency of q is equal to √0.25 = 0.5.

Answer:

In the case of the sea turtles hatching witnessed by Ethan and his family, the behavior exhibited is called an <em><u>instinctive behavior.</u></em>

<em>The sea turtle knows that, the place which they are in (Inside the shells) are not where they are supposed to be in but rather should be inside a water body. Because of these, their instinct kicks in to free themselves from the shell and head towards the ocean.</em>
