If a scientist wanted to follow mendel’s experiment with a different kind of plant, which type of plant would she examine? a pla
Dovator [93]

The correct answer is option a plant that has only two alleles for a trait.

In order to perform the Mendel's experiment, the conditions should be similar to the Mendel's actual experiment. The Mendel experiments shows the presence of two alleles controlling a single trait. So, in order to study the plant as the Mendel did, the person should choose a plant which have two alleles for a particular trait.

The plant must be able to self and cross pollinate in order to study the Mendelian characteristics accurately. IF a plant carry only recessive allele, then the effect of the dominant allele cannot be studied, so, the plant carrying only recessive allele should not be studied. Studying three allele coding for the same trait would be difficult to study the Mendelian characters, so, this plants should not be examined to study Mendel's experiment.

if an owl makes one pellet a day how many mice,voles,rats,or birds must it catch in one week ,month,or year
Leona [35]

Answer:

\large \boxed{\text{32 small animals/wk, 136/mo, and 1640/yr}}

Explanation:

The pellets from a barn owl often contain the remains of 4 or 5 small animals. Let's assume an average of 4.5 animals per day.

1. Animals per week

\text{Per week} =\dfrac{\text{1 pellet}}{\text{1 da}} \times \dfrac{\text{4.5 animals}}{\text{1 pellet }} \times \dfrac{\text{7 da}}{\text{1 wk}} = \textbf{32 animals/wk}

2. Animals per year

\text{Per year} = \dfrac{\text{32 animals}}{\text{1 year}} \times \dfrac{\text{52 wk}}{\text{1 yr}} =\textbf{1640 animals/yr}

3. Animals per month

\text{Per year} = \dfrac{\text{1640 animals}}{\text{1 year}} \times \dfrac{\text{1 yr wk}}{\text{12 mo}} = \textbf{136 animals/mo}\\\\\text{A barn owl eats $\large \boxed{\textbf{36 small animals/wk, 136/mo, and 1640/yr}}$}
