what was worked D.R Aklilu Lema ? and what is his reasarch?
Answer:
In 1964 a young Ethiopian doctor, Aklilu Lemma, discovered that suds from the fruit of a common African plant, the endod or soapberry, which African women have used as soap for centuries, act as a potent molluscicide. ... And Lemma's early research confirmed this potential.
The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
The total increase is 2754.33% increase
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [tex]\frac{[(72500 MW - 2540 MW)}{ 2540 MW }* 100%[/tex]
After solving the equation the percent change = 2754.33% increase.

Answer:
a. Gregory Mendel
Explanation:
Gregory Mendel is the father of genetics
Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.

How are Earth's structures created over time?
Answer:
Earth crust is constantly changing primarily due to plate tectonics (plate motion), but it also changes from activity on the surface from river, man made and meteorite impact. ... Continents and oceans do not ride atop the plates without changing. As the plates move and change so do the continents and oceans
Answer:
Explanation:
Earth's structures were created when the planet was first formed. Over time, its own gravitational and magnetic forces drove the Earth's core rotation. Other geological activities affected its structures; such as glacial movements, tectonic plates collisions and submersion, volcanic eruptions and so on. There were also major external events the asteroid impact that killed most lives on Earth. Human activities' impact on Earth's structures were relatively small until the recent centuries.

Answer: This means that the further away the galaxies are, the faster they are moving. ... Red-shift data provides evidence that the Universe, including space itself, is expanding. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.

Bacteria are used in food industry for the production of ?
(a)curd
(b)cheese
(c)butter
(d)all of the above
Answer:
D.) All of the above
Explanation:
Bacteria has become a major component in the processing of dairy products because of various factors. The distribution of bacteria aids factors like ripening and flavor development of cheese and curd and also aids fermentation.
Curd, cheese and butter production all involve the use of bacteria.
The bacteria commonly used to make curd is lactobacillus bacteria.
The bacteria commonly used to make cheese are lactococcus, lactobacillus and streptococcus genera
The bacteria commonly used to make butter are lactococcus and leuconostoc .

a. human arm
b. whale's flipper
c. bird's wing
d. cat's leg
Answer:
Flipper of a whale and bird's wing are homologous structures.
For more better explanation see below.
Explanation:
Flipper of Whale is homologus to the wing of a bird. Homologous organs - The structure which are similar in their morphology, anatomy, genetics and embryology, but dissimilar in their functions.
Flipper of whale and wing of bird has similar morphology and anatomy, but differ in their functions according to their species as well as the habitat where they live in.
A dolphin’s flipper, bird’s wing, cat’s leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk. What might be a risk of using this technology to produce milk?
A.
Use of the GAH may increase the availability of milk.
B.
Use of the GAH may increase the amount of hormones in the milk.
C.
Use of the GAH may provide extra milk to feed the poor.
D.
Use of the GAH may allow the farmer to reduce milk prices.
Answer:
B
Explanation:
A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
What is a genetically altered hormone(GAH)?The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.
Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
