Sea otters move into the ocean bay. The eat all the sea urchins. This change will cause the
A. Kelp to have less food
B. crabs to have less food
C. Sea ducks to have more food
D.Arctic foxes to have more food

Answers

well sea urchins are primarily food for crabs, so by sea otters eating the sea urchins crabs will end up with no good

The presence of sea otters in an ocean bay will result in a reduction in the amount of food available to carbs because they feed on sea urchins. Therefore, option (B) is correct.

What is food chain?

The linear relationship between creatures that demonstrates how they obtain energy by feeding on one another is referred to as the food chain.

The information provided in this inquiry suggests that sea otters migrate into the ocean bay and consume all of the sea urchins there.

This leads one to believe that they cut down on the food supply of another eater of urchins, such as carbs. Because of this, the introduction of sea otters into the ocean bay will result in there being less food available for carbs.

Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)

Answers

Answer:

The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.

Explanation:

a) The reaction given is:

K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl

Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,  

Moles = given mass/Molar mass

= 45/136.16

= 0.33 Moles of KHSO₄

From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,  

2 moles of KHSO₄ = 8 moles of HCl

So, moles of HCl will be,  

Moles of HCl = 8 × 0.33/2

= 1.321 moles

Now the mass of HCl is,  

Mass of HCl = Moles of HCl × Molar mass of HCl

= 1.321 × 36.46

= 48.16 grams of HCl

b) It is known that 1 mole is equal to 6.023 × 10²³ molecules

In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.  

x mole of water = 2.20 × 10²⁴ /6.022 × 10²³

= 3.653 mole of H2O

From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.  

5 moles of water = 4 moles of chlorine

3.653 moles H₂O = x moles of Cl₂

Moles of Cl₂ = 4 × 3.653 /5  

= 2.906 moles Cl₂

Now the mass of Cl₂ determined as,  

Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂

= 2.906 × 70.9

= 206 grams

What does this process lead to?
Chiasma

Answers

Answer: Chiasmata are specialized chromatin structures that link homologous chromosomes together until anaphase I (Figs. 45.1 and 45.10). They form at sites where programmed DNA breaks generated by Spo11 undergo the full recombination pathway to generate crossovers. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma generally results in improper chromosomal segregation and aneuploidy.

The soil particle size has the greatest effect on soil's capacity to retain water.

Soil particle size and organic matter (the soil's composition) are main determinants of water-holding capacity of a soil. Smaller particles (silt and clay) have a bigger surface area than larger sand particles, allowing the soil to hold more water.

For a quantitative trait explained by four loci in an additive fashion, if the four locus genotype AaBbCcDd corresponds to a phenotypic value of 32, and the four locus genotype AABBCCdd corresponds to a phenotypic value of 48, then what is the phenotypic value corresponding to the four locus genotype AABbcCDD?

Answers

Answer:

48

Explanation:

In genetics, additive effects represent a mode of quantitative inheritance that occurs when the combined effects of alleles (i.e., the variants of a gene that lead to differential expression of a phenotypic trait) at two or more loci are equal to the sum of their individual effects, contributing thus to the final phenotype. Therefore, the additive variance can be explained by the sum of the individual effects of identified loci/genes that have an additive effect on this quantitative trait. In this case, each gene shows an additive effect (equal to 8 for each dominant allele), thereby the phenotypic value corresponding to the genotype AABbCcDD will be equal to 48 (i.e., 16 + 8 + 8 + 16 = 48).
