Quién propuso el primer mecanismo de herencia a partir de la observación y la experimentación con plantas?
Answer:
Gregor Mendel
Explanation:
Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.
Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).

Look at the food web. In your response, answer the following questions
correctly for full credit: a) Identify the producers, primary consumers, and
secondary consumers in the ecosystem. b) What would happen if all the
hawks in this ecosystem were to die from an illness? c) Why would you
expect there to be fewer foxes than caterpillars in this ecosystem? d)
Which organism would have the smallest population? (8 points)
Answer:
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers.
B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash.
C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population.
D) The hawk has to be the smallest population.

Please make it in-depth with grammar and punctuation, What is a Stem Cell.
Answer:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
Examples: Embryonic stem cells, or amniotic fluid stem cells
Explanation:
I just gave you a definition with correct punctuation and two examples you could use:)

Tom described a certain phase in mitosis as follows: The centromere splits. The paired chromosomes separate and shift to the opposite sides of the cell, which stretches the cell. Which of the following phases will take place just after the phase described by Tom?
Anaphase
Metaphase
Prophase
Telophase
!!!PLEASE HELP!!!
Answer:
I'm not 100% sure, but I think its the Telophase.
Explanation:
The third phase of mitosis is called anaphase. This is when the separation starts. The centromere of each chromosome splits. The spindle fibers shorten and pull the sister chromatids apart until they are on opposite ends of the cell. Each chromatid is now a single, unreplicated chromosome. As a result of this, the cell stretches out. The phase after this is telophase.
Answer:
Ik I'm late but Telophase

Earth's northern hemisphere generally experiences warmer temperatures in July than it does in January. Which statement explains why?
A. Sunlight shines more directly on the northern hemisphere in July.
B. Sunlight in the northern hemisphere is more spread out in July.
C. The interior of the Earth heats the northern hemisphere more in July
D. The northern hemisphere is tilted away from the Sun in July
Answer:
D
Explanation:
The northern hemisphere is tilted away from the Sun in July causing Earth's northern hemisphere commonly founds warmer temperatures in July than it does in January, hence option
Why are seasonal changes occur on Earth?When Earth is tilted over its axis, this causes seasons to occur on Earth during various months, this movement around the Sun is the major cause of seasons on Earth.
In July month, the northern half of Earth tilts toward the sun, temperature of the land increases, which heat up easier than the oceans. While in January, it's difficult for the sun to heat the oceans, observing cooler average global temperatures, although the Earth is closer to the sun.
Therefore, July experiences warmer temperatures because the northern hemisphere is tilted away from the Sun in July.

Does a domain or kingdom contain more organisms?
Answer:
A domain contains more organisms
Answer:
The chart below shows how the kingdoms have changed over time.
Explanation:
As scientists began to understand more about DNA, evolutionary biologists established a new taxonomic category—the domain. A domain is a larger and more inclusive category than a kingdom. There are three domains—Bacteria, Archaea, and Eukarya.
In humans, the "A" allele codes for Type A blood, the "B" allele codes for Type B blood, and the "o" allele codes for Type O blood. "A" and "B" are both dominant to "o." A and B are codominant to each other.
What is the genotypic ratio of a cross between a mother who is heterozygous Type A and a father who is heterozygous Type B?
A. 1 AB : 1 A0:1 Bo : 1oo
B. All AB
C. 2 AA: 2 BB

how does a plant cell look under a microoscope
Plant cell under the microscope
The structure and shape of the cell are more rigid when compared to animal cells as plant cells have a rigid cell wall that provides a more solid structure to the plant cell. The shape of the plant cell is usually rectangular in shape even though some plant cells have a triangular shape.i hope it helps you:-):-)

In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
ratio be?
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1
