Write a paragraph 4-5 sentences as to which one you think is better sexual or asexual reproduction
Answer:
Asexual
Explanation:
I think Asexual reproduction is better because you only need one reproduction Creature. For example plants, they are asexual so they do not need to worry about mating. Instead they can just create more plants by doing nothing. This helps us because we get more plants in a shorter amount of time. another example of Asexual reproduction is cross-pollination which is also an amazing way of creating more plants in a shorter time.
Which of the following is an important step in the formation of a fossil?
The organism must dle of natural causes
The organism must be buried quickly
The organism must not have any fur.
The organism must be a reptile.
Answer: fossils can be formed only when a living thing is buried soon after it dies. If it is not buried soon enough, it decays. For this reason, most fossils are found in sedimentary rocks that were once under water.

Sucrase is the enzyme that catalyzes the reaction
Sucrose
Sucrose + Water ----------------------> Glucose + Fructose
If we place 5 moles of Sucrase (enzyme) and 5 moles of Sucrose in a solution of water, how many moles of each substance would we have after 10 minutes?
Answer:
0 moles of sucrose
5 moles of sucrase
5 moles of glucose
5 moles of fructose
Explanation:
Sucrase hydrolyses the glyosidic bond in a sucrose molecule to produce one glucose and one fructose, therefore;
Assuming all the sucrose has been hydrolysed in 10 minutes, you would have:
0 moles of sucrose
5 moles of sucrase
5 moles of glucose
5 moles of fructose

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number of digits (five fingers on each hand and five toes on each foot.) The couple's second child has extra digits. What is the probability that their next (third) child will have extra digits?a. 9/16.
b. 3/4.
c. 1/16.
d. 1/2.
e. 1/8.
Answer:
The correct answer is - option D. 1/2
Explanation:
Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.
In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.
Cross:
Man = Dd
Woman = dd
Their children :
D d
d Dd dd
d Dd dd
Probability of polydactyl child = 2/4 or 1/2 or 50%

Most species of deer are known to eat many different types of plants. Other than being herbivores, identify the category of species that explains how deer are very adaptable to new environments.
Answer:
they are invasive species
Explanation:
Invasive species can be defined as a category of non-indigenous species that may cause environmental harm. Invasive species have a high fecundity rate, an important dispersal capacity, highly plastic phenotypes, general habitat preferences, ability to circumvent biological controls (i.e., competitors, predators, diseases), etc. In consequence, these features become invasive species practically impossible to eliminate after introduction into a certain area and highly adaptable to new environmental conditions.
The category of species that describes how most species of deer can adapt to new environments is: invasive species.
Note the following about Invasive species:
Invasive species are usually non-native species in a new environment.They have high fecundity rate, meaning they reproduce faster.They have variety of food they can become adapted to feeding on.They have high survival rate.They can invade an habitat and disrupt the ecosystem.They are pretty difficult to control.Most species of deer is are typical examples of invasive species.
Therefore, the category of species that describes how most species of deer can adapt to new environments is: invasive species.

A biologist from another galaxy might think that automobiles are a dominant form of life on planet Earth. Automobiles move, consume gasoline and oil, and produce wastes. They are sheltered in garages and respond to stimuli. Automobiles age and break down, but new automobiles appear every year. They evolve, changing in appearance from year to year.
What arguments would you use to persuade the alien visitor that cars are not alive?
Answer:
Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.
Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.

How is energy converted and stored in the process of photosynthesis?
During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.
What is photosynthesis?Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore,During the process of photosynthesis plants convert light energy into chemical energy and can be stored in the molecular bonds of organic molecules.

Relative dating techniques have been around for hundreds of years. How did newer
absolute dating techniques change the way we look at seologic cross section
It allowed us to put reologie cross sections lo better order
It allowed us to put a formation date on some geologic crosections
It allowed us to disprove the existence of land bridges
It allowed us to start using the idea of superposition
Answer:
It allowed us to put a formation date on some geologic crossections
Explanation:
Absolute dating is a newer way of evaluating the chronology of historical events by assigning numerical ages to them. The age thus assigned might not be the exact age but it is still closer to the real age.
It is unlike relative dating techniques which simply give the chronology or order of past events instead of the exact dates. Relative dating techniques have been in use before the emergence of absolute dating techniques in the twentieth century.

Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Answer:
Since they are from different locations, unless we can radiometric Lee date them, we cannot distinguish anything between the two
Explanation:
It is not possible to determine information about the geological layers of different locations just by viewing the images, as the question above asks. This is because these two sites have different natural elements that acted on these layers and these fossils differently. In this case, making conclusions only with the visualization of the images, would not promote accurate and correct information. Ideally, a radiometric dating would be performed in both cases, so that accurate conclusions could be created.
