Variety is important for an exercise program because it __________. A. improves muscle flexibility B. reduces exercise effective

iren2701 [21]

<h2>Correct Answer is (C)</h2>

Explanation:

(C)Variety is important for an exercise program because it <u>alleviates boredom</u>.

Extending helps in expanding singular adaptability.
It is essential to survey adaptability both previously and during an exercise routine to evaluate adaptability progress.
Progress help us in improving further to towards more wellness and it will gives the individual increasingly opportunity to improve by knowing its adversaries and cons.
<em>Dynamic adaptability tests measure the measure of weight on a muscle that is moving. </em>
Dynamic adaptability tests are NOT utilized as regularly as static adaptability tests since dynamic adaptability tests include increasingly abstract estimations.

One polled (hornless) bull is bred to 3 cows. With Cow A, which is horned, a polled calf is produced. With Cow B, also horned, a

Arisa [49]

Answer:

Bull = Pp

Cow A = pp

Cow B = pp

Cow C = Pp

Explanation:

In cows polled (P) is dominant over horned (p) trait.

The bull is polled so it can be PP or Pp. Cow B is horned so it must be pp. Resultant offspring from bull X Cow B is also a horned calf (pp). This calf must have received one p from the bull. So the bull's genotype is Pp.

Cow A is also a horned cow so it must be pp. When bull X Cow A, a polled calf is produced. Since the bull's genotype is Pp and Cow A's genotype is pp, this polled calf will be Pp like the bull.

Cow C is polled like the bull so it can be PP or Pp. However on crossing with the bull (Pp) a horned calf is produced (pp). This calf got one p allele from the bull and p allele from the Cow C. So Cow C's genotype must be Pp.

Hence,

Bull = Pp

Cow A = pp

Cow B = pp

Cow C = Pp

The code for a DNA strand is CGTA. What is the complementary strand?

Simora [160]

The DNA molecule is composed of two long complementary chains of nucleotides. The complementary DNA sequence of CGTA is GCAT.

The DNA molecule is composed of two antiparallel strands of nucleotides linked together by hydrogen bonds.

In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytocine and Thymine).

In RNA, Thymine bases are replaced by Uracil bases.

According to the base pair rules, Adenine (A) always pairs with Thymine (T), whereas Cytosine (C) always pairs with Guanine (G).

In conclusion, the complementary DNA sequence of CGTA is GCAT.

Which indicators are living and non-living?

bulgar [2K]

Living indicators are species that are sensitive to changes in the environment. For example air pollution can be monitored by looking at lichen, which are sensitive to sulphur dioxide in the air. The number of lichen at a particular location indicates how clear the air is. Similarly, mayfly larvae are good indicators for water pollution because they're sensitive to the concentration of dissolved oxygen in water.

Non-living indicators are things like satellites which can measure the temperature of the sea surface, weather stations that measure atmospheric temperature, rain gauges to measure rainfall, and dissolved oxygen meters to measure concentration of dissolved oxygen in water.
