A prokaryote, or a prokaryotic cell, is a microscopic organism. Unlike eukaryotes, they lack a cell nucleus, cell membrane, or any sort of vacuoles. They are the complete opposite of eukaryotic cells.

Prokaryotes lack an organized nucleus and other membrane-bound organelles, the prokaryotic DNA is found in the central part of the cell called the nucleons, the cell size ranges from 0.1 to 5.0 in diameter, the cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shoe and prevents dehydration.

A black-eyed cat mates with an orange-eyed cat and produce all offspring with black eyes. Assuming these genes follow mendelian
stiks02 [169]

Answer:

all orange eyed

Explanation:

Mendelian genetics operate on the laws of segregation and independent assortment. This means that genes  from either parent segregates independently and are separated into gametes at an equal frequency.

Since a cross between all the black-eyed cats and orange eyed cats lead to all black eyed cats. It is safe to assume that the black eye phenotype is dominant and the orange eye phenotype is recessive. If two orange eyed cat crossed then all the offspring would be orange eyed.

dsp73

Answer:

So first understand that empirical formula refers to ratio of different atoms in lowest integer form.

To calculate this let's make mol C as our default ratio of 1* and divide everything by 0.528 mol.

Na 1.06/0.528 = 2.00757575758

C 0.528/0.528 = 1

O 1.59/0.528= 3.01136364

True/False
andrezito [222]

Answer:

This is true

These are the 3 factors:

  • Planet's Distance To Sun
  • Planet's Reflectivity
  • Planets Surface (Through Greenhouse Effect)

The thickness of the atmosphere, seems to be part of it, and I belive that is true, as it plays a role in temperature, determening wether if it can help with how warm or cold a planet is.

A planet's distance from the sun definitly plays a role, becuase depending on how far or close a planet is to the sun, the warmer it can be.

Planet's Surface goes through the process of greenhouse effect, causing a(n) planet to be able to get hotter
