Answer:
Here are the options to complete the given question
1. agriculture led to an increase in peaceful relations between groups because there was less competition
for food.
2. having reliable access to food and being able to produce more calories per unit of land available led to population increase.
3. farming for food was better for the
environment than was hunting and gathering.
4. All of the above
The answer is going to be 2
2. having reliable access to food and being able to produce more calories per unit of land available led to population increase.
Explanation:
FEEDBACK: If It Is So Bad for You, Why Farm?
sedentary agriculture increases the likelihood of increase in interpersonal violence, environmental degradation and increase in disease,
As read in the essay,
agriculture helps groups to produce a lot of food with constant access to food resulting in population and smaller birth spacing

Answer: C. Homologous chromosomes are separated in meiosis but not in mitosis.
Explanation: There are two main types of division that take place in eukaryotic cells, mitosis, and meiosis. Mitosis is the type of division that is used for growth, repair, and replacement of tissues. Therefore it is not necessary that the cells have different chromosome numbers or are varied genetically in the daughter cells in the case of mitosis.
Meiosis is the division that takes place to form the gametes for sexual reproduction. It is important in the first stages of meiosis I, to introduce variation and to halve the chromosome number.
Chromosomes numbers are halved (from 46 to 23) during meiosis I because the gametes (sperm and egg) come together and fuse during fertilization to form a zygote. When this fusion occurs (23 from the zygote and 23 from the egg), the chromosome number needs to be returned to that of the parent cell (46).
<h2>
Genetic variation is introduced during synapsis which only occurs in meiosis, not mitosis. Homologs exchange genetic information during crossing over of synapsis. Entire chromosomes also separate during meiosis I.
</h2>
At the end of meiosis, four genetically unique cells are produced with half the number of chromosomes as the parent cell (23 cromosomes) . After the process of mitosis is completed, two cells genetically identical to each pther are produced and have the same number of chromosomes as the parent cell (46 cromosomes).
Genetic variation is actually important because of changing environmental conditions.
Answer: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular.
Explanation: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular. Cells in the primary visual cortex tends to responds to a particular direction of light. There are distinct inhibitory and excitatory regions and when the bar of light is moved over the cell you hear the firing rate (noise) which depends on the direction the light moves in. When the bar of light is set at an angle or perpendicular, the inhibitory receptive field is illuminated which slows the firing rate. when the bar of light is perpendicular, it leads to both the inhibitory and excitatory regions being illuminated which can sometimes result in their firing potentials canceling out each other, which can lead to no response in firing.
