Answer:

True

Explanation:

Vocal cords are bands of smooth muscle tissue located in the larynx. When air passes through, the vocal cords vibrate.

Answer:

A,B,C,D

Explanation:

Since one parent is CC, there is no way to get cc as an outcome from this cross. However, there is also no way that all of the offspring will be CcDd, which is heterozygous for both traits. Therefore, this is the only answer choice that is incorrect.

As per observation about the  two individuals that have the following genotypes: CCDd and Ccdd the cross are options: a,b,c,d.

Since one parent is CC, there may be no manner to get cc as an final results from this cross. However, there may be additionally no manner that every one of the offspring could be CcDd, that is impure breed for each traits.

Genotype is an individual's series of genes. The time period can also talk to the 2 alleles inherited for a specific gene. The genotype is expressed while the statistics encoded within side the genes' DNA is used to make protein and RNA molecules.

Thus it is clear that all the observations are correct.

Answer:

WHAT ARE YOU TRYING TO ASK BRO

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.

Answer:

Photosynthesis-

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after

Answer:

The correct answer is -

Domain: eukarya

kingdom: fungi

Explanation:

A cell with a nucleus and cell wall made up of the chitin and does not have chloroplast, are all the characteristic features of an organism of kingdom fungi which is a group of eukaryotic organisms.

The cells with the nucleus are grouped in the domain eukarya while the prokaryotic organism does not carry a nucleus in their cell and divided into Archaea and bacteria. The chitinous cell wall without any chloroplast in the cell is one of determining features of the fungi kingdom.

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:

Explanation:

Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear

Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.

Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.

Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.

Explanation:

Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.

They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.

An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.

As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.

This range of events became known as the geological time scale.

The age of fossils and rocks is also used to map out the calibrations on the scale.

The age of fossils and rocks is determined using the process of radioactive dating.

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.
