Answer:
B. "Matter exists only when you can see it."
Explanation:
Since an atom is the smallest unit of matter, both "atoms make up matter" and "matter is made up of atoms" are true.
Living things like lions or plants are made up of atoms, which is the smallest unit of matter.
This means that by the process of elimination, B. is correct.
Matter exists regardless if you can see it or not. Humans cannot see air, but it is still made up of oxygen atoms (which are matter).
According to the table, how likely is it that blue eyes will show up in the offspring from these parents?
25%
50%
0%
100%
Answer:
0%
Explanation:
From the Punnet's square analysis of the cross between GgBb and ggBB, the following are the genotypes and the phenotypes of the offspring:
4 GgBB - solid gray fur and green eyes
4 GgBb - solid gray fur and green eyes
4 ggBB - striped gray fur and green eyes
4 ggBb - striped gray fur and green eyes
The blue eyes phenotype did not show up at all in the offspring. Hence, the probability is 0%.

2. David is growing algae in a closed bottle for an experiment. The bottle is half full of water and half full of air. David floats the bottle in a pond for three weeks. At the end of the three weeks, David notices that lots of algae grew, but the bottle did not
sink lower in the pond.
Why didn't the bottle of algae get heavier during the experiment?
A. Tiny animals in the bottle ate the growing algae.
B. The sides of the bottle got lighter as the plastic degraded.
C. The bottle has a leak, which made it lose water to the pond.
D. The growth of the algae came from the air and water in the bottle.
Answer:
The answer Is D
Explanation:
The growth of the algae came from the air and water in the bottle.
The statement (D) is correct. The growth of the algae came from the air and water in the bottle.
What is an algae?Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

The brain coordinates the __________ to a stimulus. What word completes this sentence?
Different kinds of receptors in the skin and organs are capable of recognizing both internal and exterior inputs. Neurons in the sensory system send this data to the brain.
What are the Sensory system?Assembling sensory neurons create sensory nerves, which pass through the spinal cord to the brain.
The brain and spinal cord make up a person's central nervous system (CNS). When a receptor is activated, a signal travels through the neurons, or nerve cells, to the brain.
The effector receives nerve impulses from the brain, which the brain then uses to coordinate the reaction.
A sensory system is made up of neural networks, sensory neurons (including sensory receptor cells), and brain regions involved in sensory perception.
Therefore, brain coordinates the sensory responses to a stimulus.

which type of mutation causes this translation of error that leads to cystic fibrosis?
Answer:
CF is caused by a mutation in the gene cystic fibrosis transmembrane conductance regulator (CFTR). The most common mutation, ΔF508, is a deletion (Δ signifying deletion) of three nucleotides that results in a loss of the amino acid phenylalanine (F) at the 508th position on the protein.

Margo is concerned about her family's bull. They raised him from a calf, always ensuring that he received the proper mineral supplements and giving him the same rations of food since he was young. Recently, though, Margo has noticed that he has put on an unhealthy amount of weight.
Which option describes the probable issue with Margo’s bull in the following scenario?
Available Options are:
He is drinking polluted water.
He is getting too much food.
He has an external parasite.
He suffers from maltreatment
Answer:
He is getting too much food
Explanation:
To have an unhealthy amount of bodyweight implies that Margo is suffering from Obesity. And based on scientific research, Obesity is attributed to the consumption of too much food. This can occur in both humans animal.
Hence, in this case, from the available options, the correct answer is that "He is getting too much food."
Polluted water and external parasites will only cause diseases, hence option A and C are not correct.
Obesity can never result from maltreatment. Hence option D is not correct
Answer:
he is getting too much food!

Halite has a mass of 33.0 g and a displaced volume of 17 ml. What is the density of halite?
Answer:
1.94 g/mL
Explanation:
Following Archimedes' principle, the displaced volume of an object (meaning the volume of water it displaces if completely submerged in it) is equal to the object's volume.
Thus the volume of this Halite sample is 17 mL.
The density of an object is equal to the mass divided by the volume:
density = mass / volumeWe input the data we know:
Density = 33.0 g / 17 mLAnd calculate the density:
Density = 1.94 g/mLAnswer the question please quickly

c. if you begin with one tube of e. coli, how many different types of bacteria do you expect to see in the 4th quadrant?
If we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.
To observe the colonies of a bacteria in form of quadrants, we need to follow the below-mentioned steps:
To culture bacteria, we need to transfer it to a petri dish.A petri dish is coated with a layer of agar, a jelly-like substance obtained from red algae that helps in culturing bacteria.Then the required bacteria, which is E. coli in our case is collected using a sterile rod and put on the petri dish.After that, the petri dish is heated to increase the growth of bacteria and also to ensure equitable distribution of bacteria in all four quadrants.After following the above-mentioned steps we have to cover the petri dish to avoid contamination and leave it undisturbed for a few days.When we observe the dish after a few days, we will see the bacterial colonies growing in it, as shown in the adjoining image.Thus, if we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.

natural selection favored alleles for light skin in a. south america. b. africa. c. europe. d. australia.
Option C: Natural selection favored alleles for light skin in Europe.
The theory of Natural Selection was firstly expounded by Charles Darwin. It is a key mechanism of evaluation, the change in the heritable traits, and characteristic of a population over a generation.
Natural selection favored alleles for light color skin in Europe because of the well-known correlation between skin pigmentation and distance from the equator. Relethford strongly suggests that natural selection in response to environmental factors plays an important role in the geospatial patterning of human skin pigmentation variation. The lighter level of UVR required to synthesize vitamin D, which is higher in individuals with dark color skin means the region near the equator. The European region does not receive much UVR that's why in Europe alleles of light skin are favored.

What is recombination ?
Recombination can be defined as the process where DNA fragments are under go breakage and recombined to generate new allele combinations.
This mechanism will generate genetic diversity at the gene level in which variations in the DNA sequences of various organisms will be reflected.
In the field of heredity, recombination is the process which produce gametes with new allele combinations that were absent in the gametes of previous generations.
one of the type of recombination called Intrachromosomal recombination takes place between independently assorted alleles with loci on distinct chromosomes.
Crossover occur among loci within identical chromosomes in case of intrachromosomal recombination which is essential to keep in mind that recombination takes place during meiosis in both of these situations.
