Answer:

Driving a car, smoking, burning of woods for heating purpose and cooking food.

Explanation:

Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.

Cell walls made of cellulose are present in plant cells. Human cells (skin, fingernails, muscle, etc.) do not have cell walls. Both plant and human fingernail cells have ribosomes and mitochondria. There are no cilia on either of the cells. Therefore, answer C is correct. Hope this helps! :)

Blue moon beans produce beans that are either the dominant color blue or the recessive color white The bean pods for this specie

liq [111]

Answer:

a) $0.316$

b) $0.105$

c) $0.035$

d) $0.0117$

e) $0.0039$

Explanation:

When two heterozygous plants with genotype Bb are crossed, following offspring are produced

Bb * Bb

BB, Bb, Bb, bb

so the probability of blue offspring is $\frac{3}{4}$ and the probability of white offspring is $\frac{1}{4}$

a) Probability of all 4 peas as blue

$\frac{3}{4} * \frac{3}{4} * \frac{3}{4} * \frac{3}{4} \\= \frac{81}{256} \\= 0.316$

b) Probability of 3 blue and 1 white

$\frac{3}{4} * \frac{3}{4}* \frac{3}{4}* \frac{1}{4}\\= \frac{27}{256} \\= 0.105$

c) Probability of 2 blue and 2 white

$\frac{3}{4} * \frac{3}{4}* \frac{1}{4}*\frac{1}{4}\\= 0.035$

d) Probability of 1 blue and 3 white

$\frac{3}{4} * \frac{1}{4} * \frac{1}{4}* \frac{1}{4}\\= \frac{3}{256} \\= 0.0117$

e) Probability of all white

$\frac{1}{4} * \frac{1}{4} * \frac{1}{4} * \frac{1}{4} \\= \frac{1}{256} \\= 0.0039$

How do two monosaccharides combine to form a disaccharide?

disa [49]

Answer:

A monosaccharide is made of a 6-carbon cyclic ring. 5 out of the 6 form part of the ring while the other carbon acts as a side group of the 5’ carbon in the ring. When forming a disaccharide with the next monosaccharide, the OH of the 1’ C of one monomer undergoes a condensation reaction with the OH of the 5’ C of the next monomer. This results in the formation of a glycosidic bond and the loss of a water molecule.
