Answer:

For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species

The way that looking at the carbon footprint or water footprint similar to looking at a biomass, energy, or numbers pyramid is that indicates how much energy is stored as new biomass at each trophic level, and a pyramid of biomass shows how much biomass is stored as new biomass overall.

Of all energy sources, biomass energy has the fourth-highest carbon footprint. On a life-cycle basis, biomass fuel emits 230 grams of carbon dioxide (CO2) for every kWh produced. It is not as advantageous as it might seem, it contributes to climate change, and has other detrimental environmental repercussions.

Therefore, note that at higher trophic levels, organisms are often greater in size, but because there are fewer of them, there is less biomass produced. The total mass of all trophic level creatures is known as biomass.

Biodiversity is essential to the systems that support all life, including human life, on Earth. Without a wide range of different creatures, plants, and microorganisms, we cannot have the ecological health that we rely on to provide us with the oxygen we and the food we eat. Additionally, people value nature in and of itself.

Biodiversity contributes to a availability of food , nutrition, energy, the development of medications, and the demand for freshwater, all of which together support good health. Furthermore, it supports chances for employment and leisure activities that enhance overall wellbeing.

During the carbon cycle, organic matter can be used in multiple ways by different organisms, although, this chemical compound also can be buried underground and converted into peat, coal, oil, or gas deposits. This is possible due to organisms can store this material in their structures to grow, and eventually, when they decay, for example, when a tree or an animal dies, it begins to form part of the soil in which they were before. This is the reason why currently we can extract oil from underground sinks, because of those biggest organisms that lived millions of years ago, such as the dinosaurs and ancient plants.

Having this clear, we can say that the correct answer is the first one.

Answer: Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.

Explanation: and this is what happens: The sliding of protein filaments is responsible for muscle contraction. When a motor neuron stimulates a muscle fiber, overlapping thick and thin filaments slide along one another and sarcomeres shorten. The combined shortening of many sarcomeres in many muscle fibers results in contraction of the whole muscle.

Simply look at your right side of equation and product is always there.

If a forecast states that the dew point and air temperatures are equal, the air is said to be saturated.

The dew point is the temperature to which a parcel of moist air must be cooled at constant atmospheric pressure and constant water vapor content in order for saturation to occur.

The dew point can also said to be the temperature at which the actual pressure of the vapor contained in an air parcel equals the saturation pressure, under constant atmospheric pressure.

When the dew point is equals the air temperature, the air is saturated and the relative humidity is %100.

Answer:

Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell

Explanation:

• Mitosis - the process your body cells use to make exact replicas of themselves.

• Meiosis - creates sperm or egg cells.

• Binary fission - how single-celled organisms like bacteria copy themselves

The surface ocean current relationship is balanced.

what is Geostrophic current?

At the point when the water is pushed to the right it frames the slope we describe previously. In this way, when water is moved along by the breeze it needs to be gone to one side by the Coriolis force (in the northern half of the globe) yet it should battle against gravity (attempting to climb the slope of water framed by Ekman transport). A balance is met between the Coriolis and the gravity (pressure inclination force). This balance delivers a fair stream called a Geostrophic current.

Internal skeletons are a feature of all vertebrate creatures, including fish, amphibians, reptiles, birds, and mammals.

A rigid, mineralized internal skeleton called an endoskeleton allows for movement by attaching to muscles. The axial and appendicular skeletons make up the human skeleton, which is an endoskeleton.

The axial, appendicular, and splanchnic skeletons of cows may be distinguished. The spinal column, ribs, and skull make up the axial skeleton. The cranium resembles that of a dog, except it is longer. The vertebral column extends horizontally from the base of the head to the end of the body.

Their skeletons support and shield them while also facilitating movement.

Andean-Saharan ice age (460 to 430 million a long time back)- It caused the mass termination of creatures, and after a brief term of time. The plants secured most of the surface of the soil. Because it too said that due to this tall number of plants another ice age was caused.

Karoo ice age (360 to 260 million years ago): karoo ice age worked much just like the same as that we are living in now. Antarctica solidifies over (14 million a long time back): Right now, we are living in this ice age. As the shafts of the soil are secured by ice caps.

Active transport is the form of particle transport that requires input of energy from the cell.

Active transport is the one that makes use of energy for the transport of molecules across the membrane. It is further classified into two types: primary active transport and secondary active transport. Primary active transport directly uses the energy from ATP hydrolysis for the transport. Whereas, secondary transport involves cotransport system where the energy released from the downhill transport is used for the uphill transport of molecule.

Cell is the fundamental unit of life. It is the structural unit of all the organism. Cell can either be prokaryotic or eukaryotic.

The hypothesis was regarding embryo self-inspection in early development is that viability of embryo metabolism is quite rather than active due to depletion and appearance of amino acids from culture medium.  

Early embryo consist of remarkable plasticity which means ability of separated early blastomeres to produce a whole organism. This aspect was determined from flux of radiolabeled methionine, premises that extent of DNA damage, RNA and protein content of immature oocyte are key factors whether zygote progresses to blastocyst stage.

This hypothesis was obtained from human and mouse and could be equally applied to reproduction in livestock, to get models for humans.

DNA (deoxyribonucleic acid) is the hereditary material in almost all living organisms. Most DNA is located in the nucleus.

For extraction of DNA we need  500 ml water,91% Isopropyl Alcohol (rubbing alcohol),Dishwashing liquid, Salt, Food coloring (dark colors recommended),3 clear plastic cups

Steps include  Pour 500ml water in a plastic cup

2. Add one tablespoon of salt to the water

3.dissolved the salt completely

Transfer 2 tablespoons of salt water in a clear plastic cup

2. Vigorously trill the salt water

3. Spit salt water back into the same cup

When you trill the salt water, cheek cells will come out. Add 1ml of clear dishwashing soap to the salt .It will break open the cheek cells and their nuclei walls and this causes the DNA to be released into the salt water.

1. Pour 100 ml isopropyl alcohol plastic cup.

2. Add 3 drops of food coloring, and isopropyl alcohol  in a separate clear plastic cup.

2. Add 3 drops of food coloring, mix them well

DNA is insoluble in isopropyl alcohol so it will promotes the clustering of the DNA, making them visible.
