Answer: The process of producing mature sperm is called spermatogenesis. Sperm are produced in the seminiferous tubules of the testes and become mature in the epididymis. ... Spermatogonia lining the seminiferous tubule undergo mitosis to form primary spermatocytes, which are also diploid.
Explanation:
A male generative cell is called sperm. Sperm comprises a head, body and tail. It is an important reproductive gamete in males that combines with the egg to produce offspring.
The process by which sperms are produced is called spermatogenesis.
The male reproductive cell forms in the male reproductive gland called the testes.From one male germinal cell (2n) four sperm (n) are produced.Spermatogenesis undergoes mitosis and meiosis.By the process of spermiogenesis, the spermatid receives nourishment and grows into sperms.Therefore sperm are produced by spermatogenesis.

How is the DNA code itself a homology?
Answer:
Explanation:
These fundamental similarities are most easily explained by evolutionary theory: life shares a common ancestor. ... In fact, the DNA code itself is a homology that links all life on Earth to a common ancestor. DNA and RNA possess a simple four-base code that provides the recipe for all living things.

describe some of destructive action of microbes
Answer:
A microbe is a small living thing too tiny to be seen by the naked eye and includes bacteria, fungi and viruses. Among their destructive actions is causing diseases in human beings and their livestock or plants, destruction of food by causing decomposition which might lead to hunger and other related calamities. Despite this destructive consequences, microbes are also known to have advantageous actions like helping in sewerage treatment, microbes found in the gastro-intestinal tract help in maintaining a good environment for digestion to take place. Microbes also help in ecological balance by causing decomposition of dead matter hence conserve the environment.

Based on the graph in Figure 2, identify the environmental conditions (flower density AND proportion of deep flowers) where a short- tongued bee has the greatest relative advantage over a long tongued bee. Based on the graph in Figure 2, identify the range of proportion of deep flowers at which a long tongued- bee always has an advantage over a short tongued bee.
Answer:
The correct answer would be - low flower density and low deep flower proportion
Explanation:
To find the environmental conditions for a short-tongued bee has the greatest relative advantage over long-tongued bees it is required to find the highest value of relative advantage short-tongued bees has on long-tongued bees which is the point where flower density and deep flower proportion is lowest (near the zero) according to the graph. That is represented in the graph by the peak in the white shaded portion.
To find the range of deep flower proportion at which a long-tongued bee has an advantage take a closer look to the grey shaded area where if the deep flower proportion move from 0.6 to 1 the advantage of long-tongued bees over short-tongued.
Floral density with the graph shows the low flower density and low deep flower proportion. Floral density often influences the species composition of flower visitors.
This variation in visitor species composition has significant effects on pollination success and plant fitness, poorly understood, especially in the many pollination guilds dominated by non-territorial species.
How do flower visitors diverse the traits?It explores how flower visitors with diverse traits should distribute themselves across resource patches differing in floral density.
The model predicts that species with low flower search speeds and low flower handling costs compared to competitors will usually dominate dense flower patches.
In addition, amongst flower visitors that have lower energy expenditure rates while handling flowers than while traveling, species maximizing energetic efficiency are associated with dense flower patches.
Therefore, the correct answer is low flower density and low deep flower proportion.

Joseph and Molly each have coin collections. Joseph starts with 15 coins in his collection and adds 25 coins each month. Molly starts with 25 coins in her collection and adds 25 coins each month. If Joseph and Molly continue to collect in this way, how many coins will each person have after 10 months? Enter your answers in the boxes. After 10 months, Joseph will have coins in his collection, and Molly will have coins in her collection.
Answer:
Joseph will have 265 coins and Molly will have 275 coins after ten months.
Explanation:
Joseph already has 15 coins and adds 25 coins after each month. So after ten months the total number of coins Joseph will have is [tex]15+25\times 10=265[/tex] coins.
Molly already has 25 coins and adds 25 coins after each month. So after ten months the total number of coins Joseph will have is [tex]25+25\times 10=275[/tex] coins.
So, Joseph will have 265 coins and Molly will have 275 coins after ten months.

NEED HELP ASAP!!!! Explain why the fact that invasive species did not co-evolve with the native species unbalances an ecosystem.
Answer: The invasive species unbalance an ecosystem because it takes over an ecosystem and does not let the other native species thrive while it takes over. There are many invasive species around the world even in your own town or state there is a type of fish suppose that is an invasive species to Michigan called a sea lamprey which kills fish native to the great lakes and is taking over there are also zebra muscles if you need another example
BRAINLIEST PLZ
Invasive species lack native species' population controls, such as predators, because they did not co-evolve with the other species in the ecosystem. As a result, the population of an invasive species may spread unchecked and eventually throw an ecosystem out of balance.
Unbalances in ecosystem :
A natural or human-caused disruption that throws off an ecosystem's natural balance is known as an ecological imbalance. Both natural and man-made disturbances have the potential to upset an ecosystem's delicate balance. A species' extinction or the introduction of a new species may cause an ecosystem to become ecologically unbalanced.
All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue. Both internal and external influences influence ecosystems. External variables that do not directly affect an ecosystem, such as topography, parent material that creates the soil, and climate, control the ecosystem's general structure. For instance, decomposition, root competition, shade, disturbance, succession, and the kinds of species present all regulate internal variables. While the availability of these resources within the ecosystem is normally governed by internal factors, the resource inputs are often controlled by external activities. As a result, interior variables influence ecological processes as well as being influenced by them.
