Answer: The cells and tissues support embryonic development in mammalian offsprings as these cells have the capacity to divide and differentiate.

Explanation:

Since the time from copulation till delivery of fetus several changes occur in the body of the mammalian mother including animals like cat, dog, and mouse to support the pregnancy. There are specialized totipotent cells which are proliferating specialized cells they have tendency to divide quickly and differentiate into functional types so that they can become a specialized organ or part of the body. If take an example of human which is also mammal in mother body after conception the egg gets fertilized to form sperm which changes to embryo the embryo divides and differentiate to form blastocysts and further divides and differentiate in several stages to become fetus.

The chlorophylls are well named because they do not absorb green light; instead, they permit it to be reflected or transmitted.

The name chlorophyll is derived from the Greek word khloros meaning pale green and phyllon meaning leaf. Chlorophyll is the pigmentation present in all plants that allows plants absorb energy transmitted from light.

Photosynthesis uses the energy absorbed from light to convert carbon dioxide and water molecules into glucose. As a primary pigment (photoreceptor), chlorophyll reflects green light while absorbing red and blue light in the chloroplast.

The geometric shape that will best model the cells would be a flat round disc.

The image is that of a structure containing many cells that are similar in appearance, most likely a tissue.

Each cell can be seen to be somewhat round in shape, typical of many animal cells.

Thus, in order to model such cells, flat round discs will be ideal. Using any other shape will be totally out of place.

The process of evolution causes a population's genetic makeup to change throughout time. A new species, changed genes, and novel features can arise as a result of an organism's adaptations to its environment.

When fitness costs outweigh fitness advantages, a characteristic is considered maladaptive. A trait is considered adaptive if fitness benefits outweigh costs.

Maladaptive features can arise for a variety of causes, although they can also develop as a result of environmental changes that affect an organism (due to phenomenons such as climate change.)

Therefore, adaptive and maladaptive in an organism help in survival.

Less distance may be traveled with grains whose sizes are greater and more erratic. This is because as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.

Both a reduction in particle size and rounding of initially angular pieces are effects of the protracted transport of material by water and wind current. The grains get smaller and more spherical the farther they have to travel.

Erosion, transport, and deposition all result in the formation of sedimentary rocks. A sediment's grain size provides crucial details on (1) the agent that caused the erosion/transport of the sediment and (2) the current's speed.

Therefore, as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.

Answer: To calculate the acceleration of the car, we can use the equation:

acceleration = (final velocity - initial velocity) / time

Plugging in the values given in the question, we get:

acceleration = (25 m/s - 5 m/s) / 10 s = 2 m/s^2

To calculate the resultant force exerted on the car, we can use the equation:

resultant force = mass * acceleration

Plugging in the values given in the question, we get:

resultant force = 800 kg * 2 m/s^2 = 1600 N

This is the force that must be exerted on the car to accelerate it from 5 m/s to 25 m/s in 10 s.

A) As, the accelerarion equation is V - U/t

so its 25-5/10 so its 2m/s^2

B) With the above answer in A) we can calculate the force with the equation f = m * a

so , 800*2 = 1600N

Answer:

Explanation:

vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.

Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from  a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.

Navigable Waters of the United States  For the purposes of the Clean Water Act, the term "navigable waters" includes:

all waters used in commerce, including groundwater;

all interstate waters including wetlands, mudflats, and sand-flats; and

all other waters such as lakes, rivers, streams, wetlands and sloughs.

EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters."  The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect.  In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.

Additional executive orders were issued 2015 in 2019.  Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.

Could the requirement for one or more NPDES Discharge Permit apply to my campus?

If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.

Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.

Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.

What do I have to do related to NPDES Discharge Permits?

Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.

French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.

Answer: Fossil fuels pollute the air and release carbon dioxide when burned, this increases pollution and makes climate change worse.

Answer:

The process that involves carbon moving directly from the biosphere into the geosphere is D: the decomposition of plants on the forest floor.

Explanation:

When plants die and decompose, their organic matter is broken down by decomposers (such as bacteria and fungi) into simpler compounds, including carbon. Some of this carbon is then released into the atmosphere as carbon dioxide through the process of respiration, but some of it is also incorporated into the soil. Over time, this carbon can become part of the geosphere through processes such as soil formation and the formation of sedimentary rocks.

If Earth, including its atmosphere, is defined as the system, then the surroundings are all space close to the biosphere. This system (biosphere) absorbs energy from its surroundings from solar radiation. The biosphere system releases energy to its surroundings by convection, conduction, and radiation.

The biosphere is the whole ecosystem that absorbs energy in the form of radiation from the sun and it is used to carry out all activities on the earth's planet.

Therefore, with this data, we can see that the biosphere obtains energy from solar radiation and it spread into life forms through convection and conduction.

a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.

Oxpecker numbers are projected to decline as a result of increased unlawful hunting, which will have a negative impact on rhinoceros populations.

The ticks and parasites that live on the skin of rhinoceroses and other large mammals provide the food source for oxpeckers, which are birds. By keeping the animals free of parasites and warning them of imminent danger, they offer an important service.

The number of ticks and other parasites on rhinoceroses may increase if oxpecker populations drop as a result of hunting, which could result in health issues and lower survival rates. In addition, rhinoceroses might be more susceptible to predators and other dangers without oxpeckers to provide warning sounds. So, a decline in oxpecker numbers is probably going to be bad for rhinoceros populations.

From the ratio of glucose osmole to the volume of water in the two beakers, beaker B would have the greater osmolarity.

The term osmolarity refers to the number of particles of solutes or osmoles of substances per liter of solution.  

In this case, the osmolarity of beaker A can be calculated as;

               1 osmole/6 liter

                                = 0.167 osmolar

The osmolarity of beak B can be calculated as:

                              2 osmoles/10 liter

                                        = 0.2 osmolar

Thus, beaker B with 0.2 osmolar has the greater osmolarity when compared to beaker A with 0.167 osmolar.

The process described shows no direct relation between red blood cells and the blood clotting cascade, therefore B is incorrect.

The clotting factors do not form calcium. They interact with tissue factors, as well as calcium ions interact with tissue factors too, to active factor X. Therefore, D is incorrect too.

The intrinsic pathway needs calcium ions, as they interact with factor XII to activate factor X. Therefore, C is also wrong.

Both intrinsic and extrinsic pathways needs calcium ions to activate factor X. So without calcium the cascade will be inne

The statement that best describe mass and weight is that there are both measured in kilograms.

Mass is a scalar quantity that measures the amount of matter in an object. It is a fundamental property of an object and is determined by the number of particles and their arrangement in the object.

Mass is often used interchangeably with weight, but they are different concepts. Weight is the force that an object experiences due to gravity, and is proportional to its mass and the local acceleration due to gravity. Mass is a constant, whereas weight can vary depending on the strength of the gravitational field.
