Answer:

Application Dose limits

********************************************************************************************

Effective dose (whole body), Hp (10) 50 mSv per year (or 1mSv per week)

20 mSv per year (or 0.4 mSv per week) averaged over

defined periods of five years

Annual equivalent dose to lens of the eye, Hp (3) 150 mSv

Annual equivalent dose to the skin, Hp (0.07) 500 mSv

Annual equivalent dose to hands and feet 500 mSv

what hormonal change occurs after fertilization that causes the endometrial lining to remain intact so that the fertilized egg c

tino4ka555 [31]

The answer is the pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.

The endometrial lining is where the fertilized egg implants, or burrows and attaches itself to the uterine wall, where it will continue to grow and be nourished. There are three layers of the uterus: The perimetrium is the outer layer, the myometrium is in the middle, and the endometrium is the inner layer of the uterine wall.

ExtremeBDS [4]

Answer:

The Acidophilic Microbial Community has low diversity with microorganisms primarily in Leptospirillum groups II and III and from Ferroplasma types I and II.

Explanation:

An acidophilic microorganism or plant is one which grows best in acidic conditions.

They are also referred to as microorganisms which occur in acidic natural (solfataric fields, sulphuric pools) and man-made (eg. Acid mine drainage) environments.

Acidophilic Microbes otherwise known as Acidophiles are an ecologically and economically important group.

They possess networked cellular adaptations for regulating intracellular pH. Several extracellular enzymes from acidophilic microbes are known to be functional at much lower pH than that inside the cells.

Acid stable enzymes have applications in several industries such as starch, baking, fruit juice processing, animal feed and pharmaceuticals, and some of them have already been commercialized. Acidophiles are widely used in bio-leaching of metals from low grade ores

Recent studies show that acidophiles are currently being considered to be utilized in bio-conversion and bio-remediation, as well as in microbial fuel cells to generate electricity.

Acidophilic microbes of similar characteristics are classifed in groups for ease of study and identification.

Leptospirillum Group II and II as well as Ferroplasma types I and II are groups of acidophilic microorganisms within the Acidophillic Microbial community.

Cheers!

There are 3 main categories of environmental problems that have come about because of the population growth. What are they and e

kakasveta [241]

Answer:

i)declination of resources

ii) air, water and land pollution

iii) global warming

Explanation:

As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources.we should prevent such resources for future generation also the future generation should get the chance to use such resources .the pollution is increasing day by day .we should control it .the main thing is that we should control the rapid population growth population growth should be controlled due to this global warming is increasing which is very dangerous leading to the declination of ozone layer due to which the harmful rays of sun may enter the earth which may cause various problems in us and cause various diseases due to which we may die.the main thing is that we should stop the population growth, we should conduct public awareness programmes and many more programmes to educate people. Population growth also creates deforestation as the number of people are increasing day by day they need more place to live ,they need more Land due to this they cut down the trees of forest and used to make houses there due to which deforestation takes place. we all know that deforestation is the process of cutting down trees. so the tree should not be cut down as it is the source of oxygen for all creatures living in this whole world and the main thing is that we should provide education to the children and the youth and many more. if we are educated we can stop such population growth. so the main thing is that we should stop population growth by giving education. Education is the only one way to stop such population growth.

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six

Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.
