Venus orbits the sun at an average distance of 108.2 million km and earth orbits at 149.6 million km. This makes the planet too hot to live on because it is closer to the sun and the atmospheric pressure is much higher than earths so we would be crushed if we were on Venus
Answer:
Type of radioactive decay which has occurred is an alpha decay.
Explanation:
Type of radioactive decays:
- Alpha decay is defined as the decay process in which alpha particle is released. In this process, a heavier nuclei decays into a lighter nuclei. The alpha particle released carries a charge of +2 units and a mass of 4 units.
- Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.
The released beta particle is also known as electron.
- Gamma decay In this process, an unstable nuclei releases excess energy by a spontaneous electromagnetic process and gamma -radiations are emitted. These radiations does not carry any charge and are electrically neutral.
Answer:
The correct option is: A) sympatric speciation
Explanation:
Sympatric speciation is a type of geographic mode of speciation. It refers to the evolution of two or more than two new or descendant species from the existing common descent. The new species and the ancestral species all live in the same geographic area or location.
The common example of this speciation is insects like moths that become dependent on different plants belonging to the same geographical area.
Don’t worry this is pretty easy :)
The answer is -
50% recessive alleles
50% dominate alleles
explication- find out what alleles you’re working with (heterogeneous and homogeneous)
[heterogeneous is 1 dominant and 1 recessive- homogeneous is 2 of the same alleles they can be dominant or recessive]
We’re working with a parent with heterogeneous and another parent with recessive homogeneous.
draw a allele chart

|_|_|
they look like this and take your first parents alleles and put them at the top
L s
_ _
|_|_|
|_|_|
it should look like this, then take your parent with both recessive and put them vertical to the box
L s
_ _
s |_|_|
s |_|_|
it should look like this, now you drag one letter down and one letter across for each box
L s
__ __
s|Ls|ss |

it’s should look like this when they’re done, i think you’re doing a grade below me in biology so the ratio should be 50/50 for both phenotype and genotype.
TRY TO LEARN THE VOCABULARY IT HELPS A LOT AND BASICALLY TELLS YOU THE ANSWERS!
GOOD LUCK :)
