2. Under identical environmental conditions the rate of water uptake in plant A is higher than plant B
​

Answer:

ADVANTAGES:

Bacteria are involved in production of many food products such as yogurt, cheese, pickles, etc.

Bacteria break down waste material so that our environment is not permanently cluttered with garbage, dead bodies, etc.

Bacteria are responsible for the production of important essential compounds that are necessary for life such as vitamin K production by E. coli in the gut

DISADVANTAGES:

Some bacteria cause infections or produce toxic substances that are a threat to life and/or health.

Bacteria cause spoiling of food so that it does not keep as long as we may desire.

Some bacteria may cause infections of plants, threatening our food supply or ornamental plant.

Answer:

the 2nd answer

Explanation:

Answer:

Robert Hooke discovered cell in 1665.

In selective breeding, when crossing individuals that express the desired phenotype but are heter0zygous for this character, their offspring might express the undesired trait.  

--------------------------------------  

The main goal of selective breeding is to get individuals -plants or animals- with the desired traits. These traits make them better, according to the breeder's interest. The interest is to produce individuals with the same reproductive capability, adaptability, capacity, and general phenotype as the original pure line.

To get a generation of individuals expressing the desired traits, the breeder must select parents that have the characteristics of interest. Many or some animals of the progeny might inherit the desirable phenotype.

In general, pure and almost identical animals with the desired traits are produced after many generations of inbreeding. These are the pure-bred individuals and are the product of many selective crosses.

Pure-bred (true-bred) animals are h0m0zyg0us dominant or recessive for the desirable traits. The progeny of the same line express similar phenotype and performance to the ones of their progenitors.

Many problems are associated with selective breeding and the production of pure lines.

In the exposed example, let us say that the desired trait is running speed and that there is only one autosomal gene that codes for run speed.

So, FF and Ff individuals will be able to run fast, while ff individuals will not.

Probably the breeder does not know the genotype of the animals, so this person crosses the horses according to how fast they run -phenotype-. If the breeder wants to get fast runner animals, he/she will only choose horses with this trait, which might be either FF or Ff.

If the breeder chooses two heter0zyg0us individuals, there are 75% of getting horses with the desired trait and 25% of chances to get horses with the undesired trait -h0m0zyg0us recessive genotype ff-.    

The breeder needs many generations of inbreeding to get only horses that are fast runners.

Answer:

These five major trends pose a major global threat to the planet

Explanation:

These five major trends pose a major global threat to the planet. If the world is to maintain the habitat of humans and other species. These environmental problems must be resolve. DW discussed the reasons and possible solutions.

Air pollution and climate change

Problems

Carbon overload in the atmosphere and seawater. The CO2 in the atmosphere absorbs and re-emits infrared wavelength radiation. Which causes the air, soil, and ocean surface water to warm. Which is a good thing without this, the earth would freeze. Unfortunately, there is too much carbon in the air now.

The burning of fossil fuels, agricultural deforestation, and industrial activities have increased the concentration of carbon dioxide in the atmosphere from 280 parts per million (ppm) 200 years ago to about 400 pm today. Whether it is scale or speed, this is unprecedented growth. The result: a change in the climate.

Carbon overload is just one form of air pollution caused by burning coal, oil, natural gas, and wood. The World Health Organization recently estimate that one in nine deaths in 2012 were caused by diseases caused by carcinogens and other poisons in the polluted air.

Solution:

Replace fossil fuels with renewable energy. Forest restoration. Reduce agricultural emissions. Changing industrial processes, The good news is that clean energy is abundant, but it needs to be harvest.

Many people say that it is feasible to use existing technologies to achieve a 100% renewable energy future, but the bad news is that even though renewable energy infrastructure (solar panels, wind turbines, energy storage, and power distribution systems) are widely available and Become cheaper and more efficient.

Experts have always said that our applications are not fast enough to avoid catastrophic climate damage.

Deforestation

Problem

Species-rich wild forests are destroye, especially in tropical areas. Usually to make way for cattle farms, soybean or palm oil plantations, or other monocultures. Today, about 30% of the earth’s land area covers by forests.

This is about half of what it was before agriculture started about 11,000 years ago. Approximately 7.3 million hectares (18 million acres) of forest are destroyed every year, mainly in the tropics. Therefore Tropical forests used to account for about 15% of the earth’s land surface; now they have fallen to 6% or 7%.

Solution

Most of the remainder has degraded by logging or burning. Natural forests are not only a reservoir of biodiversity but also a carbon sink. Excluding carbon from the atmosphere and ocean.

Therefore Restore degraded areas by replanting native tree species. This requires strong governance. But many tropical countries are still developing, their populations are growing. So that The rule of law is unbalanced, and cronyism and bribery are common in allocating land use.

S

Answer:

Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.

When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.

Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.

Answer:

between an animal cell and a plant cell there are some parts that are similar and carry out the same function like:

both have a cell membrane which selects what goes in the cell.

both have cytoplasm which holds the protoplasm(the living part of the cell)

both have a nucleus which carries out all cell activities and holds threads of DNA called chromosomes

both have a mitochondria which is the power house of the cell

both have golgi bodies which modify and carry proteins from sites of synthesis to sites of reaction

Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.

Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.

In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.
