Explanation:
The chromosome will stay the same organism.
The organism would be same in both homogenous and heterogenous chromosome . Therefore, switching the alleles won't change the organism if order is maintained.
What is chromosome and its type ?The thread-like chromosomes that convey the genomic information from cell to cell are formed of protein and a single DNA molecule. Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
An organism is said to be homozygous if it has identical genes on both chromosomes. It is referred to as heterozygous if the organism possesses two distinct alleles of the gene.
Therefore, if the alleles switched places but the order remains same then organism will be same too in case of homologus as well as heterologus chromosome.

9. How did life on Earth change from one period of geologic time to the next?
Answers
Answer:
Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. ... They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.
Life on Earth greatly change from one period to the next of geologic time.
The life on Earth change from one period of geologic time to the next because major changes appear on the surface of earth. Great changes in the environmental conditions leads to the change in the distribution of organisms as well as extinction of various organisms on which other organisms depend.
Due to this extinction of different organisms imbalance occurs within the ecosystem so we can conclude that life on Earth greatly change from one period to the next of geologic time.

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).
Corn heterozygous for kernel color and kernel texture are interbred resulting in the following offspring.
330 red smooth
97 red wrinkled
101 yellow smooth
32 yellow wrinkled
Perform a Contingency Chi-Square analysis and determine if kernel color is independent of kernel texture.
a. Show your DF, chi square value, and p value
b. Do you reject or fail to reject the null hypothesis?
c. Is kernel color independent of kernel texture?
Answers
Answer:
a. df = 3, chi-square = 1.7333, p value = 7.815
b. we fail to reject null hypothesis
c. it is independent of kernel texture
Explanation:
h0; there is independence
h1; no independence
9:3:3:1 this is the phenotypic ratio
9+3+3+1 = 16
330 red smooth + 97 red wrinkled + 101 yellow smooth + 32 yellow wrinkled
total observed = 560
1. the degree of freedom = n-1
n =4, 4-1 = 3
to get the chi square computation
(O-E)²/E
expected value for red smooth,
9/16 x 560 = 315
chisquare = (330-315)²/315 = 0.7143
expected for red wrinkled
3/16*560 = 105
chisquare = (97-105)²/105 = 0.6095
expected for yellow smooth
3/16*560 = 105
chisquare = (101-105)²/105 = 0.1524
expected for yelow wrinkled
1/16 * 560 = 35
chisquare = (32-35)²/35 = 0.2571
total chisquare = 0.7143+0.6095+0.1524+0.2571
= 1.7333
with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815
1.7333 < 7.815
so we fail to reject the null
c. we conclude that kernel color is independent of kernel texture

How might a plant population be affected by the construction of a road through a forest? In your answer, consider how things such as pollution from automobiles, runoff from roadways, or an increase in sunlight might affect the plant populations that live in the forest.
Answers
Answer:
Roads and traffic affect wildlife populations in three major ways, by (i) increasing mortality, (ii) decreasing habitat amount and quality and (iii) fragmenting populations into smaller sub‐populations which are more vulnerable to local extinction.
Explanation:
A plant population affected by the construction of a road through a forest by:-
Roads create improved access to forests, which can increase predation rates from hunters.Animals may move to avoid traffic noise, increasing their vulnerability to predation by other animals.Fragmentation can have a severe impact on wildlife. Reductions in habitat may lead to increased competition among species and more limited resources.Pollution that affect the plant populations that live in the forest include:-
Automobiles: - Pollutants from automobile deposit on leaves, blocking the stomata and eventually affecting transpiration.
These depositions hinder CO2 absorption and decrease photosynthesis .This affect the growth of plants and their productivity.Runoff from roadways:- It contain salts which when come in contact with the plant roots injure them.
it increase water stressit also affect water qualityIt affect the mineral nutrition.Increase in sunlight:- It can bleach out the color of plant's flower and foliage.

Explanation:
37. Positive feedback differs from negative feedback in that A) positive feedback benefits the organism, whereas negative feedback is detrimental. B) the effector's response in positive feedback is in the same direction as the initiating stimulus rather than opposite to it. C) the effector's response increases some parameter (such as temperature), whereas in negative feedback it decreases. D) positive feedback systems have only effectors, whereas negative feedback systems have only receptors. E) positive feedback systems have control centers that are lacking in negative feedback systems.
Answers
Answer:
B) the effector's response in positive feedback is in the same direction as the initiating stimulus rather than opposite to it
Explanation:
Two major mechanisms are used by target cells to relay information about the quantity and effect of an hormone produced by an endocrine gland back to its source. These mechanisms are: positive and negative mechanism.
- Positive mechanism occurs in such a way that the effector's response favors that of the original stimulus while in Negative feedback, the effector's response counters or opposes the original or initiating stimulus.
For example, if the pancreas (endocrine gland) releases insulin hormone to the cells, the cells send a positive feedback to make the pancreas proceed with the production of insulin while a negative feedback will make pancreas reduce or stop the production of insulin.

short note on occurrence of water in different source and state
Answers
Answer:
Water circulates in nature through a continuous and permanent process called the hydrological cycle or the water cycle. In this process the physical and biological elements of nature intervene, atmosphere, rain, water from lakes, rivers and seas, soil and vegetation. Water is in several states: solid state, which is ice. Liquid state, includes groundwater, which is found in the deep layers of the soil, and surface water, which includes innumerable rivers, and a gaseous state, which is found in air and clouds.
Explanation:
Water covers 71% of the earth's surface. The water cycle comprises three phases: Evaporation, filling the atmosphere with large amounts of water vapor (gaseous state). Condensation, forming water droplets in the form of a cloud or mist. Precipitation: the water vapor that is the clouds cools and precipitates in the form of rain, hail or snow. When the rain falls, some of the water is retained in the dense foliage and branches of the trees. Another seeps into the ground, forming the layers of underground water and the other part drains superficially forming streams, rivers or increasing their flow. All water, through evaporation, can change back to the gaseous state, restarting the water cycle. On our planet, water is located mainly in the oceans where 96.5% of total water is concentrated, glaciers and polar caps have 1.74%, underground deposits in (aquifers), and continental glaciers represent the 1.72% and the remaining 0.04% is distributed in decreasing order between lakes, soil moisture, atmosphere, reservoirs, rivers and living beings. Water is found in nature in three different forms or states in: solid state, such as ice, hail or snow, liquid state, such as the water we consume and the water of the seas, rivers and lakes and in the gaseous, when it forms clouds or steam that comes out of boiling water.
