.answer:

petit arm

explanation:

all human chromosomes have 2 arms, the p (short) arm and the q (long) arm. they are separated from each other only by a primary constriction, the centromere, the point at which the chromosome is attached to the spindle during cell division.

the symbol "p" stands for "petit", small in French, while "q" was chosen merely because it was the next letter in the alphabet.

vova2212 [387]
From what I can tell, The answer is either A or B. Mammals have what is called an Endoskeleton, which means that their skeletons are inside their bodies. A way to remember this is Exo- is similar to exit and when you exit something then you are going outside. Endo- sounds like into, which can relate to being on the inside. Insects have Exoskeletons, which are made from Chitin. Now Agonists are also called Prime Mover muscles, which means they are practically the same thing.

What is the main function of environmental policy? a. prevent the use of natural resources b. reduce human impact on the environ
Sergeeva-Olga [200]

The most important function of the environmental policy is to keep a track of human activities that can impact the environment.

Further explanation:

The environmental policy is a set of rules and regulations, laws, and policies made up by the government or organization regarding environmental issues. Ecosystem management, biodiversity maintenance, and water and air pollution are some of the issues concerning the environment. The policies which involve regulation of substances like pesticides and other industrial wastes also come under environmental policy. One of the most deliberate roles of environmental policy is to regulate and direct human activities so as to prevent the environment and its resources from the harmful effects. These policies also make sure that humans are not affected by the harmful changes in their environments.

The government intervention through policies for the protection of the environment is necessary as natural resources are not owned by any one person and tend to be over-exploited. When the waste products are produced by the factor along with the main product, it is released into the nearby water body, thereby leaving it contaminated. This water might be used by other people for drinking purposes but due to the contamination the society has to bear the extra cost of cleaning the water. Therefore, the environmental policy has provision which states that the dumping of factory waste must be done only when it is free of any hazardous chemicals. Another problem is that the common people have the incentive to utilize natural resources to any extent. With the least interference from the government the resources will be overused.

Sam started his morning walk from the location indicated by the point below.
mel-nik [20]

Answer:

(-1,-3) on the coordinate grid.

Explanation:

The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).

He walked 5 units south and met his friend Joshua.

So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).

Sam then walked 2 units east, where he met his friend, Ethan.

So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).

So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.
