Answer:
The correct answer is - the brown allele is not independent from the black allele and disappears in the F1 generation.
Explanation:
IN this question it is given that there is a cross between pure black and pure brown breed and the F1 generation has all-black coat offspring and their self cross produced 961 black and 317 brown.
The black coat offspring is three times than the brown coat offspring in F2 generation which means they have 3:1 ratio that comes in the self cross of heterozygous only there for the F1 generation black coat offspring have the heterozygous genotype for the trait,
Thus, the brown allele is not independent of the black allele and disappears in the F1 generation.

Which type of cell are found in the leaves of a tree?
O eukaryotic animal
O chloroplastic
O prokaryotic
O eukaryotic plant
Answer:
Palisade parenchyma cells
Explanation:
Palisade parenchyma cells are elogated cells located in many leaves just below the epidermal tissue. Spongy mesophyll cells occur below the one or two layers of palisade cells. Ray parenchyma cells occur in wood rays, the structures that transport materials laterally within a woody stem.
Answer:
eukaryotic plant

The pathophysiology of osteomalacia involves a. collagen breakdown in the bone matrix. b. inadequate mineralization in the osteoid. c. crowding of cells in the osteoid. d. increased osteoclast activity.
Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.

The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?
Answer: The percent increase in the mass of cylinder of beetroot is 8%.
Explanation:
To calculate the percent increase in the mass of cylinder, we use the equation:
[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]
We are given:
Final mass of the cylinder = 2.7 g
Initial mass of the cylinder = 2.5 g
Putting values in above equation, we get:
[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]
Hence, the percent increase in the mass of cylinder of beetroot is 8%.
What heat transfer method gives plants the energy they need for photosynthesis to take place?
Conduction
Convection
Radiation
Glucose
Answer: radiation
Explanation:
Answer:
Radiation
Explanation:
plants need radiation to produce sunlight in order for them to carry out photosynthesis
the type needed is photosynthetically active radiation (PAR)
does the radiation from the sun to the sand lower the kinetic energy of the sand
Which two structures are found at the outside of the cell?
Answer:
All cells share common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell.

Why is your body going through physical and chemical changes?
Answer:
(MY) body is only going through chemical changes because of my digestive juices, my saliva, and brain functions.
Explanation:
{MY} body isn't going through many physical changes other than my body slowly breaking down on a nuclear level every day slowly just like everybody else that's why nobody dies of old age, its just the teardown of their body eventaully giving out

Scientists find fossils of a wide variety of dinosaur species throughout Mesozoic rocks, which date from approximately 250 million to 65 million years ago. Above the Mesozoic rocks lie Cenozoic rocks, which date from approximately 65 million years ago to the present day. No dinosaur fossils exist in the overlying Cenozoic rocks.
What is the most likely explanation for the lack of dinosaur fossils in Cenozoic rocks?
A. The dinosaurs' biological diversity increased in the Cenozoic Era.
B. Dinosaurs adapted in the Cenozoic Era so that their bodies could no longer be preserved as fossils.
C. There was a mass extinction of dinosaur species at the end of the Mesozoic Era.
D. There was a mass extinction of dinosaur species at the end of the Cenozoic Era.

If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.
from his monohybrid crosses, Mendel developed his first law
Answer:
Im confused but if your asking for Medel's first law it would be states that for the pair of alleles an individual has of some gene (or at some genetic locus), one is a copy of a randomly chosen one in the father of the individual, and the other if a copy of a randomly chosen one in the mother, and that a randomly chosen one will be copied

How many daughter cells does mitosis produce?
A) 2.
B) 4
C) 23
D) 46
Answer:
A) 2.
I hope it helps :)
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
