Answer:
The correct answers are:
Analogous structures do not indicate a common ancestor. Analogous structures have the same function but a different structure. An example of an analogous structure is the wing of a bat and a butterfly.
Explanation:
Analogous structures are the structures that have a similar function in various organisms but their anatomic structure is different from one another in reality. Analogous structures are do not indicate a common ancestor.
An analogous structures example is the wings of the bat and butterfly as they are both used for flying but their structure is different anatomically from one another.
The defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.
Answer:
Greenhouse gases absorb radiation from the sun and re-radiate it back toward the <u>atmosphere,</u> which helps to maintain a normal range of <u>temperature</u> on Earth.
Greenhouse are glass house which are used to grow crops in regions exhibiting extreme cold temperatures and snow fall. The soil in these regions are frozen therefore, are not suitable for plant growth. These glass houses trap the sunlight which is used by the plants for photosynthesis and growth. Some gases like methane, carbon dioxide, carbon monoxide, sulphur and nitrogen dioxide are released into the atmosphere. These gases maintains the range of temperature of atmosphere.
Answer:
Option B. makes the most sense.
Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
