An elephant has a long, powerful trunk. According to the ideas of Lamarck, how did the trait of long, powerful trunks develop in elephants?
Answer:
Gradually, as generations of elephants continued to selectively use and develop their trunks.
Explanation:
Jean-Baptiste Lamarck was famous French Naturalist. He was a soldier, a biologist and an academic. He gave an early theory of evolution known as the theory of Lamarckism.
It was Lamarck who first believed that elephants earlier had small trunks. But eventual when there was scarcity of food and water, the elephants stretched out its trunk to reached out for food such as trees and also water. And as a result their offspring inherited long and powerful trunk.
In his theory of Lamarckism, he believed that the species passes on its traits to the offspring which they acquired through their use in their lifetime. In this case, the elephants might have used their trunks in such a way that they became long and strong over time and they passed tis trait to their babies.

the process which takes place in guard cells but not in other epidermal cells is?
Answer:
guard cells chloroplasts , involved in the photosynthesis where epidermal cells are living cells covering the outside surface of the herbaceous plants they contain a thick covering of cutting which reduces the water loss from Plants epidermal cells in roots are specialized for water and ion absorption don't know if it helped but good luck
Photosynthesis
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Difference in guard and epidermal Cells:Two guard cells form a stoma, controlling the gas exchange of the plant by regulating the size of the stoma whereas epidermal cells provide a protection to the plant from the external environment.
Photosynthesis does not take place in epidermal cell because:The epidermal cells that make up this skin are transparent. As most epidermal cells lack chloroplasts, they can't perform photosynthesis, or the use of sunlight to convert carbon dioxide and water into glucose and oxygen.

Punnett square is given below and on the base of the result of Punnett square, Millie should mate with Denver to get three different colors of puppies.
Explanation:
The question says that Millie has a genotype BB*, which is a combination or heterozygous condition of dark brown allele B and white allele B*, now cross with Denver (light brown color):
Cross 1:
B B*
B BB BB*
B* BB* B*B*
the results is : 25% dark brown, 50% light brown and 25% white.
cross 2: with Charley (white color)
B B*
B* BB* B*B*
B* BB* B*B*
there is only white and light brown puppies produced
Thus, the correct answer is - Denver.
Question 21 (1 point) Sustainable use is often defined as the use of natural resources at a rate that meets the needs of the present human population but which also allows future generations to use the resource to meet their needs. Which of these BEST illustrates the concept of sustainable use? A fishing trawler uses a large net to catch a school of small fish A logging company reseeds and replants in a forested area after cutting down trees for timber Crops are rotated in a farmer's field to maximize grain yields Coal is mined using underground tunnels to avoid the destruction of surface soils by strip mining
Answer:
A logging company reseeds and replants in a forested area after cutting down trees for timber
Explanation:
Answer:
Sustainability is the capacity to endure in a relatively ongoing way across various domains of life.[1] In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.[2][failed verification] For many in the field, sustainability is defined through the following interconnected domains or pillars: environmental, economic and social,[3] which according to Fritjof Capra,[4] is based on the principles of systems thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political.[5][6] According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."[7][8] Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (seeing development as inherently unsustainable).[9]

10. are a type of producer found in aquatic environments. In a particular lake, the phytoplankton have begun to
reproduce much more rapidly and grow much faster, causing a green "bloom” to cover the whole surface of the
lake. Which of the following is the most likely cause of this bloom"?
Answer: I think that it would be C because blooms are due to eutrophication, which means that there are high levels of phosphate in the water. Phosphate is a main ingredient in pesticides, which can run-off into rivers.
Do primers create a single stranded section of dna
Answer:
Yes
Explanation:
A primer is a short, single-stranded DNA sequence used in the polymerase chain reaction (PCR) technique. In the PCR method, a pair of primers is used to hybridize with the sample DNA and define the region of the DNA that will be amplified. Primers are also referred to as oligonucleotides.
