The data support the conclusion that reducing emissions leads to improvement in air quality for the common air pollutants monitored by the EPA.

The Environmental Protection Agency (EPA) is a federal agency of the United States government that was established in 1970 to protect human health and the environment. The EPA's mission is to ensure that all Americans have clean air to breathe, clean water to drink, and safe land to live and work on. The agency is responsible for setting and enforcing national standards for air and water quality, as well as for managing toxic waste and other pollutants.

The EPA also works with other federal agencies, states, tribes, and local governments to address environmental challenges, such as climate change, ozone depletion, and exposure to hazardous substances. The EPA uses a range of tools and programs, including research and development, regulation, partnerships, and education and outreach, to achieve its mission. The agency also provides information and technical assistance to help individuals, communities, and businesses protect the environment and public health.

At point A, the birth rate is much higher than the death rate hence there is an increase in the population.

The term population has to do with the number of organisms that live in a particular habitat at a particular time. There are two main forces that control the population of a place and this is the birth rate and the death rate.

The birth rate refers to the number of the new individual organisms that are added to the habitat while the death rate refers to the number of organisms that leave the habitat. This could be used to decipher the trend in the population as discussed below.

Given that a population in which the birth rate is far higher than the death rate would experience an explosion, such a population would now grow in leaps and bounds and it would be difficult to contain the number of individuals therein.

Endosymbiotic theory

Explanation:

The concept that hypothesized that small bacteria were engulfed by larger cells to become the mitochondrion  and eventually become a eukaryotic cell is known as symbiogenesis or the endosymbiotic theory.

The endosymbiotic theory argues that organelles like mitochondrion and the chloroplast found in modern-day eukaryotic cells were formerly prokaryotic microbes. These microbes got ingested by primitive, amoeba-like eukaryotic cells that were first formed but instead of dying, the engulfed microbes found a way to symbiotically coexist with their hosts, eventually forming the organelles - aerobic microbes forming the mitochondrion and photosynthetic microbes formed the chloroplast.

Explanation:

The presence of cilia, flagella and pseudopods improve the chances of survival of a protist by increasing the likelihood of obtaining nutrients. Thus, the correct option is A.

Locomotion is the basic act or ability of something to transport or move itself from one place to another. Many protist species have the presence of some type of locomotory organelles on their body which are easily visible under a light microscope. A protists can move by gliding or floating, and by use of organelles such as flagella or cilia.

Protists use these locomotory organelles to find food, a mate, a suitable habitat or to survive and escape form the predators. Types of Movements involved in locomotion include axial and appendicular.

Therefore, the correct option is A.

Answer:

They are all stages of mitosis, which is cell division (for new cells for repair and growth)

interphase- the longest stage of the process. The DNA in the chromosomes copies itself, ready to split for mitosis. ALL 23 pairs copies itself so now there is 46 pairs of chromosomes (23 for each new cell).

prophase- The DNA in the chromosomes are more visible now, and the membrane around the nucleus disappears ready for the next stage

metaphase- Chromosomes and their copies line up in the middle of the cell, so that they could be pulled apart in the next stage

anaphase- Spindle fibres attach themselves to either end of the chromosome. They are then pulled apart to either ends of the cell. 23 on one side, 23 on another.

telophase- membranes form around the 23 pairs of chromosomes at their end of the cell. Two new daughter cells are produced. The cell membrane pinches in and divides the cells in two.

Answer:

true I think I just guessed

TRUE : Prokaryotic cells  generally have a higher surface area to volume ratio than eukaryotic cells

Eukaryotic cells are larger and complex when compared to prokaryotic cells which makes its surface area to volume ratio to be smaller than that of prokaryotic cells. cells are classified based on the arrangement  of their cell structures.

Prokaryotic cells are found in smaller organisms like Bacteria while Eukaryotic cells are found in larger organisms like Humans and Plants.

Hence we can conclude that based on the complexity and size of the Eukaryotic cell, the prokaryotic cells generally have a higher surface area to volume ratio.
