Answer:

A

Explanation:

DNA is used to make mRNA, which is then used alongside tRNA to make a polypeptide chain. This chain folds to make a protein.

Answer:

A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.

Explanation:

Answer:

Mendel studied the genetics of pea plants.

Explanation:

Mendel looked at the pea plants in his monastery garden to determine genetics. He found that some plants had white flowers, while some did not, and he used that discovery to determine the genetics of the plants.

Answer:

Explanation:

The presence of mitochondria  and an extensive endoplasmic reticulum are the features that are important for adaptations of the plasma cell because plasma cells (white blood cells) secrete immune proteins also called antibodies which only formed due to the presence of endoplasmic reticulum whose function is to formed proteins for the cell so that's why plasma cells have large sized endoplasmic reticulum.

Answer:

The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.

Here are some fact about sharks that i found cool

#1

Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey

#2

Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.

#3

Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.

#4

Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.

#5

Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.

#6

There are over 500 species of shark.

#7

It is believed that each whale shark's pattern is unique, like a human's fingerprint.

#8

Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears

#9

According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.

#10

Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.

#11

Whale sharks are the world’s biggest fish.

#12

Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.

#13

Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.

#14

Sharks predate the dinosaurs by 200 million years.

#15

Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

Answer:

the material that strengthens their cell walls

Explanation:

Chytrids originate from the kingdom fungi and a division known as Chytridiomycota. They contain a feature of unique characteristics by the presence of the chitin and the cellulose cell wall. The chitin made up the component of their cell wall in fungi but in Chytrids, the cellulose helps to strengthens their cell walls.

Answer:

A. the material that strengthens their cell walls

Answer:

Oxygen is an electronegative

Explanation:

Not only is it because in the chemical equation for water there is 2 hydrogen atoms and 1 oxygen atom, but they also share their electrons to fill their outermost levels and that are attracted together.

Nutrient depletion of soils is a widespread soil degradation phenomenon that occurs as a consequence of soil erosion (it is the topsoil in which generally most soil nutrients are present that erodes fastest) but also because of poor management practices, such as slash and burn and other subsistence agricultural.

Answer:

i would say chemical but if im wrong im super sorry!!

Explanation:

Answer:

The ethics of artificially inserting traits in animals has been in the practice for years in the form of selective breeding, but should scientists really be editing DNA to the extent they are today? I don't believe they should. Life itself should construct itself without us interfering. Making a brand new plant just because it looks nice doesn't account for many factors, including the fact that it could be harmful to nearby plants if pollinated. In addition, generic engineering costs quite a lot of money, which should be used on other more cost effective methods, such as improving agriculture rather than creating a whole new plant that could harm entire crops. Genetic engineering isn't a necessity and humans should not play God with plant and animal life.

this is the answer for only first page.

homologous, diploid,gametes,haploid

the same thing as what the other person said.

di=2

hap=1

remember that for diploid and haploid

Answer:

For question 1 the answer is respiratory, and for question 2 is circulatory

Answer: (1) Circulatory (2) Respiratory

The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth's surface temperature rises.
