In Mendel's experiments with pea plants, the allele for tall pea plants was dominant and the allele for short pea plants was recessive. When did Mendel see short pea plants?
A. when the plants had two dominant alleles for height
B. when the dominant allele for tall plants was not present
C. when the plants had both a dominant allele and a recessive allele
D. when the pea plants produced yellow seeds
PLS HELP!
Answer:
B
Explanation:
if the reccesive trait is what you want then you cannot have any dominant alleles present
how widespread was yellow fever during the 1600s and 1700s?
Answer:
The first yellow fever outbreaks in the United States occurred in late 1690s. Nearly 100 years later, in the late summer of 1793, refugees from a yellow fever epidemic in the Caribbean fled to Philadelphia. Within weeks, people throughout the city were experiencing symptoms.
In the area illustrated, what process is evident over time?
In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.
Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).
In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.
Generally, there are three (3) main types of ecological succession and these include:
Primary successionSecondary successionCyclic successionFrom the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.

In an ecosystem, a deer consumes grass. What percentage of energy will the deer acquire from the grass? 0. 1% 1% 10% 100%.
In an ecosystem, the energy is transferred between the organisms participating in the food webs from producers and consumers.
The percentage of energy transferred to the deer after feeding on the grass is 10%.
The 10% law of the energy states that:
1. The food chain at each trophic level passes or transmits only 10% of the energy and 90% of the energy is lost as heat.
2. The amount of energy at each trophic level decreases, such that the producers if consuming the 100 J of energy, the deers or primary consumers at the first trophic level will have only 10% of the energy.
Thus, the deer will possess only 10% of the energy at each trophic level, following the 10% law.
The correct answer is Option C.

Como saber que algo está compuesto por una célula
Respuesta:
Las células están formadas por un núcleo y un citoplasma, encerradas por una pared delgada llamada membrana, que las separa de su entorno. Las células vegetales también tienen núcleo, citoplasma y membrana celular. La principal diferencia entre una célula vegetal y una animal es que las células vegetales tienen una vacuola, un cloroplasto y una pared celular.

Question:
How to know that something is made up of a cell
Answer:
Cells are made up of a nucleus, and a cytoplasm, enclosed by a thin wall called a membrane, which separates it from its surroundings. Plant cells have a nucleus, cytoplasm, and a cell membrane too. The main difference between a plant and an animal cell is that plant cells have a vacuole, chloroplast, and a cell wall.

cellular respiration how cells harvest energy
Answer:
Cellular Respiration: a process able to extract a large amount of energy from food molecules. In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.

The illustration below represents____,
which is responsible for genetic diversity.
Answer: Crossing over
Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️
The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.
What is Crossing over?Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.
Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.
Therefore, the correct option is B.

kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

what is the name of the trait that hides or masks another genetic trait?
A dominant trait is the name of the trait that hides or masks another genetic trait.
What do you mean by dominant trait?Dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
The dominant trait is the one that is the first to appear or express itself visibly in the organism. Example: In human beings, we observe V-shaped hairline.
Dominant individuals are often most influential in their social groups, affecting movement, opinion, and performance across species and contexts.
