In your Punnett Square activity, you chose beads which represented
genes and used Punnett Squares to determine possible offspring. If
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring out of 4 have the yellow kernel phenotype?
please please!!

Answers

Answer 1

Answer:

Two out of four offsprings have the yellow kernel phenotype.

Explanation:

The information that we have is that one parent's genotype is yellow bead (Y) and blue bead (B), and the other parent's genotype is blue bead (B) and blue bead (B).

Parent 1: YB

parent2: BB

If we make a Punnett Square, we can see that two out of four offspring will have the yellow phenotype.

  ║ B   ║ B   ║

Y║ YB ║ YB ║

B ║ BB  ║ BB ║

Answer 2

The offspring out of 4 have the yellow kernel phenotype in the given case would be - two or 50%

We are given that the kernel color is represented by two beads, yellow and blue beads.

Let us consider yellow bead be represented as Y and blue bead be represented as y. Yellow color is dominant over blue kernel color.parent 1 has a genotype of a yellow bead and a blue bead represented as Yy.parent 2 has a genotype of the blue bead and blue bead, i.e, yy.

The cross can be given as,

Genotype Y y

y   Yy     yy

y    Yy     yy

Now, two of the four offspring have Yy genotypes.

Thus, 2/4 or 50% of the offspring have a yellow kernel phenotype.

In which structure would you expect to find a chloroplast?
A. Blood cell from a dog
B. Cell from sunflower leaf
C. Human skin cell
D. Liver cell from a penguin

Answers

Answer:

b.cell from a sunflower leaf

The structure that can have chloroplast is the cell from sunflower leaf. The correct option is B.

What is chloroplast?

Chloroplasts are chlorophyll-containing organelles found in plant cells; they are necessary for Earth life because photosynthesis occurs in chloroplasts.

Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, as well as other plastids.

Chloroplasts are plant cell organelles that use photosynthetic energy to convert light energy into reasonably stable chemical energy.

They survive life on Earth by doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the generation of fatty acids and membrane lipids.

Chloroplasts are found in all green plants and algae. Chloroplasts can also be found in photosynthesis that don't appear green, such as giant kelp's brown blades or certain plants' red leaves.

Thus, the correct option is B.

2. What fluvial landform is A?

Answers

Answer:

The landform marked with A is an ox-bow lake.

Explanation:

In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.

The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

Stagnant, shallow areas of water-saturated soil, where the rate of photosynthesis is low, are best characterized as:______.

Answers

Answer:

The correct answer is - bogs.

Explanation:

Bogs or boglands is a wetland that is made up of dead organic matter such as dead plants or parts of the plants like mosses, majority time it is a thick carpet of sphagnum moss. All these form spongy peat which is stagnant.

Most of the water present in this wetland comes from rainfall instead of runoff or streams from the groundwater which makes it a wetland with a shallow area of water-saturated soil. This wetland is known for its less photosynthesis.

In which situation might a gene pool contain an allele that causes a lethal
disease?
A. If the allele is in the mitochondria
B. If the allele is expressed after reproduction has occurred
C. If the allele is on the Y chromosome
D. If the allele is expressed in its dominant form

Answers

correct answer is B; if the allele is expressed after reproduction has occurred.

The situation in which a gene pool contain an allele that causes a lethal disease is: (B) If the allele is expressed after reproduction has occurred.

When the allele is expressed after reproduction has occurred, individuals carrying the lethal allele can reproduce and pass on the allele before the disease is expressed. Since the disease may not manifest until later in life or after reproduction has occurred, the allele can persist in the gene pool without being selected against. Over generations, the allele frequency can remain relatively stable, leading to the presence of the lethal allele in the gene pool.

An allele can be defined as a variant form of gene. Alleles can exist in different forms due to changes in the DNA sequence. These changes can be substitutions, deletions, insertions, or other types of genetic mutations.

What do you think humans and arthropods have in common?

Answers

Muscle and nerve cells are also alike in human beings and arthropods.  Both have brains, hearts, digestive tracts, reproductive organs, and muscle groups that do more or less the same matters.

Arthropods are invertebrate animals having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. they may be outstanding by means of their jointed limbs and cuticle made from chitin, frequently mineralized with calcium carbonate.

Arthropods are beneficial for different meals that humans eat, especially thru the pollination of plants. greater than 100 food plants are pollinated via arthropods on a yearly basis. Bees, one of the foremost plant pollinators, also produce honey.

Arthropods also are invaluable to human beings, as they're used in many one-of-a-kind human-made products. Examples are: Bees produce honey and their honeycombs contain beeswax, broadly used for making candles, fixtures wax and polishes, waxed papers, antiseptics, and fillings for surgical uses.

What is the function of a pollen tube?
to lead sperm cells into the ovary
to create more pollen
to create sperm cells
to lead egg cells to the sperm cells

Answers

Answer:

The function of the pollen tube is to lead sperm cells into the ovary.

Explanation:

In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.

The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.

The other options are not correct because the pollen tube:

Do not create more pollen. Do not create more male spermatophytes. Does not lead the eggs to the male spermatophytes.

Answer: to lead sperm cells into the ovary .

Explanation: There needs to be a way for the sperm cells formed by the pollen's generative nucleus to reach the egg cells that are found in the ovary.

What is the estimated age of Earth?
A.4.6x10^6
B.4.6x10^7
C.4.6x10^8
D.4.6x10^9

Answers

Answer:

D: 4.6 x [tex]10^{9}[/tex]

Explanation:

4.6 x 10^{9} = 4,600,000,000

Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}

The estimated age of Earth is 4.6x10⁹ years (D).

Scientists estimate the age of Earth through various methods, including radiometric dating of rocks and minerals. By analyzing the isotopes present in rocks and minerals, scientists can determine the decay rates of radioactive isotopes and calculate the time since the formation of those rocks.

Based on extensive studies and evidence, the current estimated age of Earth is approximately 4.6 billion years (4.6x10^9 years). This estimation is supported by multiple lines of evidence, including radiometric dating of rocks from different geological formations, lunar samples brought back from the Moon, and meteorites.

The age of 4.6 billion years is consistent with the age of the oldest rocks found on Earth's surface and the ages of the Moon and meteorites, which are believed to have formed around the same time as Earth. These dating methods provide a reliable framework for understanding Earth's geological history and the processes that have shaped our planet over billions of years.

It's important to note that scientific estimates and understanding of Earth's age continue to evolve as new evidence and research emerge. However, the current consensus among scientists is that the age of Earth is approximately 4.6 billion years, as indicated by extensive geological and radiometric dating studies.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.
