What do you think the color of the pea plants has to do with genes?
Answer:
According to Mendel Gregor, he analyzed two plants can make a different offspring. It depends on the alleles. I hope this helped!
Explanation:
Answer:
The instructions for making a pea plant are found in its genes. Each gene has the instructions for one small part of the pea plant. There is a gene that determines the color of the peas the plant will produce. These genes can come in all different versions.

Question 23 (6 points)
Sea Urchins are aquatic mammals that dive down to catch and eat sea urchins. Sea
urchins hunt the sea floor to catch and eat starfish. Starfish feed off of kelp forests
under the sea.
When sea otters overpopulate they clean out the sea urchins very quickly. This
allows the starfish to overpopulate and eat too much of the kelp forests.
Answer the following questions for 2 points each:
1. Name the TWO organisms that act as Carnivores in the ecosystem described
above.
2. Identify the ecological roles of the other TWO organisms.
3. Identify which of the four organisms above would be considered a keystone
species. Explain why.
Answer: 1. Sea urchins and sea otters
2. They are prey for carnivores.
3. Sea otters, star fish
Explanation:
Sea urchins and sea otters are carnivores as they eat on the flesh of starfish and sea urchins respectively.
Starfish feed on the kelp forests which are the producers in the food chain and the starfish is the primary consumer and prey for sea urchins. So, starfish and kelp forests are the prey in the marine ecosystem.
Keystone species is the one which controls the population of other inferior species in an ecosystem. Here, sea otters consume sea urchins so the population of sea urchins remained in control Starfish controls the population of kelp forest.

How do cancer cells differ from normal cells? Select all that apply.
A
they do not stop at checkpoints
B
they condense their DNA into chromosomes for cell division
C
they have uncontrolled growth
D
they go through the S phase
Answer: A and B
Explanation:
Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth. So, options A and C are correct.
What do you mean by Cancerous cells?Cancerous cells may be defined as an abnormal cell that doesn't follow the regulations of the cell cycle. They get multiply at a rapid speed.
Normal cells follow a typical cell cycle. They grow, divide and finally die. But cancer cells do not follow the cell cycle, they do not undergo apoptosis, and they continuously multiply at a rapid pace.
Therefore, Cancers cells differ from normal cells because they do not stop at checkpoints and they have uncontrolled growth.

The atoms of certain element each contain 36 protons and 8 valence electrons. Which statement correctly identifies this element and describes its chmical reactivity?
Answer:
This question lacks options, the options are:
A The element is krypton, Kr, and it is not very reactive.
B The element is chlorine, Cl, and it is highly reactive.
C The element is krypton, Kr, and it is highly reactive.
D The element is chlorine, Cl, and it is not very reactive.
The correct answer is A
Explanation:
An atom is identified by its atomic number, which is the number of protons it contains. In this question, it is said that the atoms of a certain element each contain 36 protons. Using the periodic table, the element with atomic no. 36 is KRYPTON.
Also, Krypton posseses 8 valence electrons in its outer shell. In accordance to the octet rule, Krypton has no further need to engage in any chemical reaction to fill its electron shell because it is already filled (8 valence electrons). This accounts for the reason Krypton belongs to "Noble gases" and very unreactive.

Beginning around 1750,the global human population began to grow at much faster then it had in the years before this time.What caused this to change in the population growth rate?
Answer:
The cartogram is made up of squares, each of which represents half a million people of a country’s population. The 11.5 million Belgians are represented by 23 squares; the 49.5 million Colombians are represented by 99 squares; the 1.415 billion people in China are represented by 2830 squares; and the entire world population of 7.633 billion people in 2018 is represented by the total sum of 15,266 squares. It started in 1798, to the 1800. This period is when the human population began to grow at a faster rate then any other time in history. The answer is 300 years ago.
Explanation : Births - usually measured using the birth rate (number of live births per 1,000 of the population per year). Deaths - usually measured using the death rate (number of deaths per 1,000 of the population per year). Migration - the movement of people in and out of an area.

The rebuilding of an ecosystem after a natural disaster

Explain why secondary succession is a faster process than primary succession.
Answer:
Ecological succession happens when new life takes over an environment. ... Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment
Ecological restoration aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. Disturbances are environmental changes that alter ecosystem structure and function. Common disturbances include logging, damming rivers, intense grazing, hurricanes, floods, and fire
Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate
If brown hair is represented by the allele "B" and blond hair is represented by the allele "b" then what must the genotype(s) be of someone who has brown hair?
Answer:
Bb or BB
Explanation:
since brown hair was the dominant allele it only has to have one big B to serve as a heterozygous dominant trait. Therefore, the person has brown hair. If you were looking for blond hair it would have to be bb because it is a recessive trait and you need two recessive traits to make up a certain genetic trait.
