Otrada [13]3 years ago
6 0

Answer:

Growth rate becomes negative.

Explanation:

Growth rate becomes negative when a mammal population exceeding its carrying capacity because the environment can't sustain the extra population due to limited resources of that environment. Every environment has a limited resources such as food, water and shelter etc, and due to these limited resources limited number of organism can live in that environment so when the population exceeds, the growth becomes negative.

9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black
lisabon 2012 [21]

Answer:

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black: \frac{3}{8}

rough white: \frac{3}{8}

smooth black: \frac{1}{8}

smooth white: \frac{1}{8}

The cells in this part of a plant form long, vertical tubes. What is the most
Soloha48 [4]

Answer:

The cells present in the stem are part of the xylem and phloem conductive tissues. They are characterized by being elongated and in tubular form because they transport the substances, the xylem transports  water and  inorganic mineral sales that the root absorbs from the soil. The phloem is responsible for transporting substances synthesized in photosynthesis.

Its tubular and elongated shape facilitates the transport of these substances

The qrs complex is associated with ________. the qrs complex is associated with ________. depolarization of the ventricular sept
Zepler [3.9K]

In a typical ECG (Electrocardiogram) the first wave obtained is P wave; The P wave represents the depolarization of the atria. After this, the QRS complex is formed. The QRS wave represents the depolarization of the ventricles.  During the depolarization phase, the ventricles contracts and pushes the blood into the atria. Hence, the correct answer is depolarization of the ventricles.
