The one variable affects another happens in experiments. Thus, option D is correct.
What is experiment?An experiment, or experimental research, is a research method in which the researcher manipulates or changes the value of one variable, (the independent variable) and measures the variable that is considered the dependent variable, in order to find how the change affects it.
The other three posible answers, observational research, survey and case study are also research methods, but the researcher can't manipulate or control any of the variables, these methods are used only to measure a specific variable.
Therefore, The one variable affects another happens in experiments. Thus, option D is correct.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.

What is an observation? What do you use to make an observation?
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
8. In chickens, brown feathers are dominant over red feathers. Suppose we cross two heterozygous chickens.

Phenotypes of offspring:
Plz help me
Answer:
Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.
Explanation:
Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.
The cross can be represented by a Punnett Square:
Bb X Bb cross
alleles B b
B BB Bb
b Bb bb
Where the result is:
Genotypes:
Bb, 50% BB, 25% bb, 25%Phenotypes:
Brown feathers, 75% Red feathers, 25%.In this case, the probability of having brown or red feathers is 3:1.

[tex]\Huge\text{Pisces or Fishes}[/tex]
Pisces or Class Fish is the largest group of chordates which includes 25000 species of fishes. Study of fishes is called Ichthyology.
Fish is an aquatic gill breathing gnathostomates whose stramlined body is provided with paired fins and covered over dermal scales.
Super Class pisces is divided into two classes:
Chondrichthyes Osteichthyes _____________________________________
[tex]\Huge\textbf{Chondrichthyes}[/tex]
Chondrichthyes are Cartilagineous fishes. This class is also called Elasmobronchi. It has exclusively marine fishes with endoskeleton made of cartilage. Their skin has tiny shark enamel coated denticles called Placoid Scales. They are heterocercal and Mouth is present at ventral to tail fins. They have exposed 5 gills on each sides.
Example Shark, Ray fishes, Dog dish etc
_____________________________________[tex]\Huge\textbf{Osteichthyes}[/tex]
These fishes are Bony Fishes. This group is also called Teleostomi, They are found in both marine and fresh water. Their endoskeleton is made up of bones. Their skin has thin bony plates called cycloid or ctenoid. Their gills are covered with outer skin called operculum. Tain fin is homocercal and mouth is present at anterior tip.
Examples Sea Horse, Gold fish, Eel etc
_____________________________________[tex]\huge\text{Similarities}[/tex]They have gill to breath Streamlined body to move in fast moving water All fishes are cold-blooded.

Chondrichthyes are exclusively marine fishes while Osteichthyes are both fresh water and marine water living.The skeleton of Chondrichthyes is made of cartilage while the skeleton of Osteichthyes is made of bones.The gills of Chondrichthyes is NOT covered with operculum while the gills of Osteichthyes are covered with outer skin operculum. The skin of Chondrichthyes has tiny shark enamel coated denticles called Placoid Scales while the skin of Osteichthyes has thin bony plates called cycloid or ctenoid.The tail of Chondrichthyes is Heterocercal and mouth is ventral to the tail fins while the tail of Osteichthyes is homocercal and the mouth is present at anterior tip._____________________________________Best Regards,'Borz'1 Invasive plant species affect the interactions of living and nonliving components

A) cumulus clouds
B) greenhouse effect
C) transpiration
D) convection
And I need an explanation
Answer:im guessing its the greenhouse effect
Explanation:The Earth's atmosphere is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). ...

A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.What is a zero of the following function: f(x)=3x-15?
