Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

Based on this exert, I'd say Option C

Kazeer [188]

Answer: A sum total of all living and non-living elements and their effects which influence human life is known as environment. An environmental aspect is an element of an organization's activities, products, and services that can interact with the environment. These can include discharges to water, emissions to air, waste and use of natural resources and materials.

2.Answer: 1. Environment plays an important role in healthy living and the existence of life on planet earth.

2. Earth is a home for different living species and we all are dependent on the environment for food, air, water, and other needs.

3.Everything that surrounds us constitutes our environment. .

4. The environment plays an important role in the healthy living of human beings.

astraxan [27]

Complete question:

17. In the 1950’s a young woman sued film star/director Charlie Chaplin for parental support of her illegitimate child. Charlie Chaplin’s blood type was already on record as type AB. The mother of the child had type A (AO) and her son had type O blood (OO).

a. Complete a Punnett square for the possible cross of Charlie and the mother.

b. The judge ruled in favor of the mother and ordered Charlie Chaplin to pay child support costs of the child. Was the judge correct in his decision based on blood typing evidence? Explain why or why not. *refer to any Punnett squares to support your answer.

Answer:

The judge committed a mistake in his decision. There are <u>no chances</u> for this couple to have a child who has 0 blood type.

Explanation:

<u>Available data:</u>

Charlie Chaplin’s blood type was AB
The mother of the child had type A (AO)
The son had type O blood (OO).

Cross: Charlie Chaplin x The Woman

Parental) IAIB x IAi

Gametes) IA IB IA i

Punnett square) IA IB

IA IAIA IAIB

i IAi IBi

F1) 1/4 = 25% of the progeny would have IAIA genotype, blood type A

1/4 = 25% of the progeny would have IAi genotype, blood type A

1/4 = 25% of the progeny would have IAIB genotype, blood type AB

1/4 = 25% of the progeny wouldl have IBi genotype, blood type B

According to the results of the cross observed in the Punnett square, there are no chances for this couple to have a child who has 0 blood type.

Blood type 0 can only be produced by two recessive alleles i, one inherited from each parent. The mother could provide the recessive allele because she is IBi, but Chaplin could not pass to his progeny any recessive allele.

The judge committed a mistake in his decision.

What are the steps in filament theory

Inessa [10]

Answer and Explanation:

The steps of the sliding filament theory are:

Muscle activation: breakdown of energy (ATP) by myosin.

Before contraction begins, myosin is only associated with a molecule of energy (ATP), which myosin breaks down into its component molecules (ADP + P) causing myosin to change shape.

Muscle contraction: cross-bridge formation

The shape change allows myosin to bind an adjacent actin, creating a cross-bridge.

Recharging: power (pulling) stroke

The cross-bridge formation causes myosin to release ADP+P, change shape, and to pull (slide) actin closer to the center of the myosin molecule.

Relaxaction: cross-bridge detachment

The completion of the pulling stroke further changes the shape of myosin. This allows myosin and ATP to bind, which causes myosin to release actin, destroying the cross-bridge. The cycle is now ready to begin again.

The repeated cycling through these steps generates force (i.e., step 2: cross-bridge formation) and changes in muscle length (i.e., step 3: power stroke), which are necessary to muscle contraction.

A mutation that involves one or a few nucleotides is called

inysia [295]

A mutation that involves one or a few nucleotides is called

a) mutagen

b) inversion

c) point mutation

d) translocation

Answer:

c) point mutation

Explanation:

When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.

Answer:

adhesion

Explanation:

Its just like Water drops on a pine needle or on anything else, Cohesion is when water is attracted to water. Therefor its Adhesion, because that's when water is attracted to other things or substances.
