Crossing a BB parent with a bb parent results in
Answer:
All dominant allele children with the genotype Bb
Explanation:
Use a punnet square to see how. It's quite simple when u learn the logistics :)
Hope this Helps!
When the two parental genotypes BB and bb are crossed, the genotype of all [tex]F_1[/tex] plants is Bb.
What is Genotype?An organism's genotype is defined as the complete set of genetic material that can also be used to refer to alleles or variants that occur in a particular gene or genetic locus.
The term "genotype" describes the genetic makeup of an organism as it describes the complete set of genes of an organism. This term can be used to refer to alleles, or variants of genes, carried by an organism.
When two organisms like BB parent crossed with bb parent, the offsprings that will produce is Bb.
Thus, when the two parental genotypes BB and bb are crossed, the genotype of all [tex]F_1[/tex] plants is Bb.

A. Eukaryotic cells can eat prokaryotic cells by engulfing them with
cell membranes.
B. All prokaryotic cells are covered by a stiff cell wall that protects
them.
C. Their chloroplasts contain DNA that is similar to that of
prokaryotes.
D. Chains of amino acids form inside tiny bubbles filled with organic
molecules.
Answer:
Their chloroplasts contain DNA that is similar to that of

Explanation:
This is based on the theory that the membrane bound organelles of chloroplast and mitochondria which are peculiar to Eukaryotas evolved from bacteria by endosymbiosis. Thus bacteria contain the DNA of these organism Evidently, these organism (Eukaryotas) must have cohabited with bacteriA some time ago
The soil in a flower pot, the amount of water added to the pot, the amount of
sunlight received by the plant, the amount and type of fertilizer given, and the
temperature of the air surrounding the pot all make up the plant's
a. ecosystems
b. habitat
c. abiotic factors
d. biotic factors
Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples may be light, water, and temperature in a terrestrial habitat, hence option C is correct.
What are abiotic factors?Abiotic variables are non-living elements that have an impact on the survival, development, and existence of living things, including plants.
We may concentrate on the water as one of these abiotic elements even though there are many others that are equally significant and have a part to play.
Water is one of, if not the most, critical abiotic factors since it is essential for plant existence. Depending on how severe the absence of water is, it will be a limiting factor for a plant's growth or even life.
Therefore, abiotic factors are non-living components of an ecosystem that influence their surroundings, hence option C is correct.

Which of these is a form of nonrenewable energy?
O A. Fossil fuel energy
O B. Solar energy
C. Wind energy
O D. Hydroelectric energy
Answer:
Fossil fuel energy
Explanation:
This is because oil from fossils take a millions of years to form and people won't be able to wait millions of years
Fossil fuel energy is a form of non-renewable form of energy. Thus, the correct option will be A.
What is Non-renewable energy?A non-renewable energy resource is a natural resource which cannot be readily replaced by the natural means at a particular pace which is quick enough to keep up with the consumption of the energy resource. An example of the non-renewable energy resource is a carbon-based fossil fuel. The original organic matter with the aid of heat energy and pressure generally becomes a fuel such as the oil or natural gas.
There are four major types of the nonrenewable resources which include oil, natural gas, coal, and the nuclear energy. Oil, natural gas, and coal are collectively known as the fossil fuels. Fossil fuels were formed within the Earth from the dead plants and animals over a period of millions of years and hence are named as the fossil fuels.
Therefore, the correct option will be A.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis, because energy is being used to move molecules with the concentration gradient. B.Active transport, because energy is being used to move molecules against the concentration gradient. C.Facilitated diffusion, because energy is being used to move molecules with the concentration gradient.
Answer:
B. Active Transport
Explanation:
The concentration gradient is from high to low. The molecules are moving from low to high which is against the concentration gradient. Also, the ATP symbol is shown pointing, and ATP is energy.
The description that best identifies the type of cellular transport being depicted in the image would be that of active transport because energy is being used to move molecules against a concentration gradient.
There are basically 2 types of cellular transports:
PassiveActivePassive cellular transports are those that do not require energy in any form. They include osmosis, the movement of water molecules from the region of high to low water potential via a semi-permeable membrane, and simple/facilitated diffusion, the movement of molecules from regions of high concentration to regions of low concentration.
Active transports are those movements of materials in and out of the cell that requires the expedition of energy in the form of ATP. It is usually the movement of materials against their concentration gradients. Examples include vesicle transport, ion pumps, etc.
In the illustration, the direction of movement of the molecules (by the arrow) indicates that it is against the concentration gradient. Also, the burning of ATP gives further credence that is an active system of cellular transportation.

.Specific processes must take place within the cell for protein synthesis to occur. The processes that take place within a cell for protein synthesis to occur. Which occurs during translation but not during transcription? A DNA template is used to create an mRNA strand. A tRNA template is used to create a DNA strand. A tRNA template is used to create an mRNA strand. An mRNA template is used to create an amino acid chain.
Answer:
An mRNA template is used to create an amino acid chain.
Explanation:
Transcription is the first step in the protein synthesis process. Translation is the second.
Overall, the central dogma of biology is DNA->RNA->protein.
Transcription is that first step, DNA to RNA, and translation is RNA to protein: think of it like nucleic acids can just be transcribed, but nucleic acid to protein is like a whole different language, so it has to be translated. So the correct answer here is that mRNA is used to make amino acid chain (aka protein), which happens only in translation.
Which option describes cations?
Answer:
D
Explanation:
A cation is a positively charge ion, such as a sodium ion, as when it becomes an ion, it gives away electrons, becoming positively charged.
The opposite is an anion, which is a negatively charged ion, such as oxygen as it receives elections from the cation when forming an ionic bond.
Cations are the positively charged ions.
What are cations?A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them.
The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
Therefore, Cations are the positively charged ions.

D. an animal that eats only herbs
An herbivore is an animal or organism that gets energy from eating only plants, which is present in option B. Examples are the goat, cow, etc., and they eat the producers, such as the plants.
What is the role of the herbivore?The herbivore is the animal that directly eats the plants of the ecosystem, which are later eaten up by the carnivore, and the herbivore gets more energy than the carnivore as they get energy directly from the plant source. The herbivore only eats plants, and the different ecosystems have different herbivores, such as the land ecosystem, which has the goat, elephant, cow, etc.
