Answer:
It will take train B a longer time to come to come to rest at the target train station
Explanation:
We know that train B has a higher mass compared to train A.
The same force is applied by the brake of the train to bring them to rest.
- From Newton's second law of motion; force is a product of mass and acceleration:
Force = mass x acceleration
Now, the more the mass of a body, the higher the force applied to cause it to accelerate. To bring such a body to rest, a higher force must also be applied to it
Answer:
the answer is Z
Explanation:
Z is a tissue that is made up of cells joined collectively and the second smallest level of organization in the human body.
Horticulturalist’s best option is clone the desired tulip so there will be no genetic variations.
Explanation:
Cloning is a process by which replica of organism is made without having any genetically variations. It is done carefully to avoid any variations in the office bring that may be related to physical or genetic structure.
The process of cloning should be done under the supervision of expert to avoid any error which could lead to the variation in genetic structure. It is very necessary for the amateur horticulturalist who desires to have dual apps without any genetic variation to perform cloning.
Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
