➜ Mendel conducted breeding experiments with garden peas:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
Note: Here, F1 means First fillial generation and F2 means Second fillial generation.
Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. ... Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants...We used to take this character, we may choose different.
what is the shape of the bacteria thiobacillus
Answer:
this bacteria has a rod shaped form
Answer:
rod-shaped
Explanation:
Bacteria in the genus Thiobacilli are classified within the order Pseudomonadales. They are small, rod-shaped cells (0.5 by 1–3.0 µm) which may be motile or nonmotile. Motility is due to a single polar flagellum. Bergey's Manual (1957) lists nine species, most of which are aerobic.

Answer:

Explanation:
In cherry tomatoes, red color (R) is dominant to yellow color (r). If two heterozygous plants are crossed, what percentage of the offspring will be yellow?
Answer:
50
Explanation:
If you cross two heterozygous tomato plants, you get four base genotypes of (Respectively,) RR, Rr, Rr, and rr. That makes your percentage A. 50%.
Explain h0mozygous and heter0zygous?If a dominant red fruit (RR) plant is crossed with a recessive over yellow fruit (rr), then the phenotype will be red fruit and the genotype Rr. It is a case of complete dominance.
In diploid organisms (2n), an individual is homo-zygous when it carries two copies of the same gene variant (i.e., the same allele).
Moreover, an individual is heter0zygous when it carries two different alleles for the same gene locus.
In complete dominance, the dominant allele completely masks the expression of the recessive allele in heter0zygous individuals.
Thus, That makes your percentage A. 50%.

__________ is a method of studying complex systems by reducing the components that are studied (e.g. studying cells in culture and using those results to understand what is going on in a complex disease).
Select one:
a.
emergent properties
b.
systems biology
c.
genomics
d.
reductionism
Answer: A.
Explanation: "An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood. You will need the whole heart to be able to pump blood."
Explanation for the incorrect answer:
"Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach to biological research. "

Answer:
The gene that has the wrong plan for the important growth factor in Norrie's Disease is on the X chromosome. If a girl (XX) has one X chromosome that does not work she will be protected from developing Norrie's Disease because she has a protective spare.
Explanation:

Answer: Norrie disease almost entirely affects males.
Explanation: Due to the X-linked recessive pattern of inheritance, Norrie disease affects almost entirely males. Only in very rare cases, females have been diagnosed with Norrie disease; cases of symptomatic female carriers have been reported.
A table with four organisms and their primary role in an ecosystem is shown.
Common Name
Role in Ecosystem
Kingfisher
Carnivore
Black fly larvae
Herbivore
Trout
Carnivore
Algae
Producer
Based on the table, which trophic pyramid is correct?
Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.
Explanation:
The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.
For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.
Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.
The producer, the algae, is found at the base of the pyramid, and the black fly larva (an herbivore) is found above it. On the third trophic level, there are carnivores such as the trout, and the kingfisher is on the fourth level.
What is the ecological pyramid?The ecological pyramid is divided into several types, including the pyramid of numbers, the pyramid of energy, and the pyramid of biomass, and the characteristics of the pyramid vary by ecosystem. The pyramid consists of producers at the basal level, which is the algae, and they produce most of the energy in the ecosystem.
The energy and food are then transferred to the second trophic level, the herbivore level of black fly larvae. The third level is the carnivore level (primary carnivore), where the trout eats the herbivore (black fly larva), and the fourth level is the kingfisher, where it eats the primary carnivore, which is the trout, and this results in the pyramid starting with a broad base of producers and eventually narrowing towards the apex.
Hence, the pyramid begins with a producer (algea), then the herbivore, then the trout, and finally the kingfisher.
