The photo below shows four different types of respirators: two filtering facepieces, a half-face respirator, and a full-face respirator. All of these respirators can work as filtering respirators, but only the half-face and full-face respirators can carry a chemical cartridge.

A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR).
igomit [66]
So I don’t see answer choices here, but your answer is 50% of the offspring will be homozygous dominant with RR, and 100% of them will carry a homozygous dominant gene of Rr

If you take the two sets and put them into a punnett square, it would look like this (image attached):

When the two sets of alleles are crossed, you would end up with half of your pairs being fully dominant (RR), and the other half being dominant while containing a recessive gene (Rr). Since there’s only one recessive gene in these pairs, it gets overridden and the pair itself is dominant.

So your answer is 50% will be homozygous dominant with RR!

Content practice a acceleration lesson 3 answers
sdas [7]

Acceleration is defined as the rate of change in the speed of a moving body or vehicle typically.

<u>Explanation:</u>

In the branch of mechanics, the aspect of acceleration is considered to be a property of the vector. And acceleration always occurs in a specific positive direction.

The formula for determining acceleration is change in the rate of velocity over a specific time, and is therefore measured as the ratio of delta velocity by delta time unit.

  \text {acceleration}=\frac{\text {velocity}}{\text {time}}=\frac{\left(\frac{\text {distance}}{\text {time}}\right)}{\text {time}}=\frac{\text {distance}}{\text {time}^{2}}\left(\mathrm{m} / \mathrm{s}^{2}\right)

The unit of acceleration is distance per time unit squared or m / second squared.

Phylogenies based on sequences from organellar genomes and nuclear genomes from the same group of species yield phylogenetic tre
mojhsa [17]
<h2>Evolution of phylogenies </h2>

Explanation:

  • The genome of the endosymbiont is all the more firmly identified with individuals from the gathering in which it initially developed, while the nuclear genome of the inundating living being has its own evolutionary trajectory.  
  • The accumulation of various inheritable attributes after some time which prompted the arrangement of another species  
  • Nuclear and organellar genes advanced at various rates, clouding developmental connections.  
  • Some mitochondrial genomes have been decreased definitely in size, losing a large number of the protein genes encoded in creature mtDNA just as a few or all mtDNA-encoded tRNA genes.
  • At ∼6 kb in size, the mitochondrial genome of Plasmodium falciparum (human intestinal sickness parasite) and related apicomplexans is the littlest known, harboring just three protein genes, profoundly divided and improved little subunit (SSU) and enormous subunit (LSU) rRNA genes, and no tRNA genes.
  • In stamped differentiate, inside land plants, mtDNA has extended generously in size (>200 kb) if not in coding limit, with the biggest known mitochondrial genome right now.
