A small, potentially living object was found. For this object to be considered alive, the object must________.
ycow [4]

Answer:

For the object of to be considered alive , it must have DNA and all the characteristics of living things.

Explanation:

If one is to determine whether the object is alive or not the object should possess all the properties of living things. firstly, it should have the genetic material the DNA without which the cell can't be alive or the nucleus in case of PROKARYOTES. it should have the ability to reproduce, move , to grow and to excrete without which it would not be considered alive.

Yeast cells are recovered from a fermentation broth by using a tubular centrifuge. Sixty percent of the cells are recovered at a
Serga [27]

Answer:

\\ \omega = 5033.22 \ rpm

Explanation:

Given that:

R_1 = 0.6\\\\R_2 = 0.95\\\\\omega_1 = 4000 \ rpm\\\\\omega_2 = ???\\\\Q_1 = 12\ l/min\\\\Q_2 =  12\ l/min

For a continuous centrifuge ; solid recovery R ∝ \frac{\omega^2}{Q}

where;

ω = angular velocity of the centrifuge in rpm

Q = flow rate

SO;

R_1 \alpha \frac{4000^2}{12}

R_2 \alpha  \frac{\omega^2}{12}

\frac{R_1}{R_2} = \frac{4000^2}{12}  ÷  \frac{\omega^2 }{12}

\frac{R_1}{R_2} = \frac{4000^2}{12} * \frac{12}{\omega^2}

\frac{R_1}{R_2} = \frac{4000^2}{\omega^2}\\\\\frac{0.6}{0.95} = \frac{4000^2}{\omega^2}

{\omega^2} = \frac{4000^2*0.95}{0.6}\\\\\\{\omega} = \sqrt{ \frac{4000^2*0.95}{0.6}}\\\\\\ \omega = 5033.22 \ rpm

The two cells formed at the end of meiosis I have chromosomes that are
Shkiper50 [21]

The right answer is C.

Meiosis and fertilization contribute to the stability of the species.

Meiosis ensures the passage of the diploid phase to the haploid phase. It follows a phase of DNA replication and consists of two successive divisions, the second is not preceded by a duplication of DNA. These two divisions lead, from a diploid mother cell (2n chromosomes), to four haploid daughter cells, the gametes (n chromosomes).

Meiosis and fertilization are at the origin of genetic mixing.

During meiosis, intra- and interchromosomal mixing occurs (inducing a genetic diversity between the daughter cells, and they are systematically different from their mother cell).

*Intrachromosomal mixing, or crossing-over recombination, takes place between paired homologous chromosomes during the prophase of the first meiosis division;

*Interchromosomal mixing is due to the independent migration of the homologous chromosomes of each pair during anaphase of the first division. It therefore concerns chromosomes reworked by the intrachromosomal mixing that preceded it.
