Answer:
1. 36500 kcals
2. Producers
Explanation:
As organisms in one trophic level feeds on another organism in another trophic level, one must bear in mind that only 10% of available energy at each trophic level is transferred.
According to this question, the secondary consumer trophic level has 365 kcals of energy. Since there are primary consumer and producer trophic levels before this, it means that 100 times of energy was previously available at the producer level. Hence, 365 kcal × 100 = 36500 kcal of energy is available at producer level.
2. The producer level has the most available energy (kcal) among the trophic levels because they get it directly from the sun and are the first participants of the energy transfer.

Which best describes a bacteriophage
Bacteriophages are a special class of viruses that infect and spread only within bacteria.
Bacterium refers to bacteria, while "phage" means to eat or devour. Together, these two words form the term "bacteriophage". Highly specialized viruses called bacteriophages attach to the surface of bacterial cells and introduce their genetic material into the host bacterium.
Once the bacteriophage's genetic material enters the bacterial machinery, it causes it to make multiple copies of the phage particles. The host bacterium is eventually killed, and freshly produced phages are freed to infect additional bacterial cells. Nature is full of bacteriophages, which are important for managing bacterial populations and building microbial communities.

James needed to have his hernia surgically repaired. This can be done through laparoscopic surgery. The surgeon must cut through to the herniated area and put a Teflon mesh underneath the hernia to close it off and provide more support to the area. Use your knowledge of anatomy to select the correct sequence of structures that would be cut for this procedure. Make sure you select the structures in the order they would be cut by the surgeon.
Answer:
The structures that the surgeon will cut to place the Teflon mesh from external to internal are:
Skin,
hypodermis,
subcutaneous fat,
the external oblique aponeurosis,
the internal oblique,
the transverse abdominal,
the peritoneum.
Explanation:
For the surgeon to put the Teflon mesh underneath the hernia, the professional has to cut the most external organ, which is the skin, with all its layers, epidermis, dermis, and hypodermis. Underneath this tissue is the subcutaneous fat, which protects the muscles, regulates the temperature, and stores energy. Subcutaneous fat is different in every person. Some can have a lot of it and others a thin layer. The next cut will be on aponeurosis, which is a tissue that surrounds muscles. Then we have the internal abdominal oblique, which is in the anterior area of the abdomen. Below it, it is the transverse abdominal, and then the peritoneum, which is the tissue that holds the organs. In a hernia, it has a hole where the organs push through. So, the surgeon has to put a Teflon mesh to close it.
does lemon juice have more or less H+ ions than it has OH- ions? explain
Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. ( source : https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ )

is it more beneficial for humans to undergo sexual reproduction than asexual reproduction?
Answer:Advantages and disadvantages of sexual and asexual reproduction
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Examples in the natural world
Bacterial reproduction
Bacteria, such as E. coli, reproduce asexually. An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die. The population would be wiped out. The only way for variation to be introduced into the population is by random mutation.
Rabbit reproduction
Most animals reproduce sexually, for example, rabbits. The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage. If a disease were to hit the rabbit population, then perhaps not all of the rabbits would be affected because of the variation in the population. This means that some individuals would survive and be able to reproduce and generate more offspring.
Asexual and sexual reproduction in fungi
Some fungi are able to reproduce both sexually and asexually. Fungi reproduce using spores which they release into the environment. A new fungus will grow from the spore. The Coprinus cinereus fungus can produce spores by sexual reproduction to help create variation in the species. This method of reproduction is advantageous when the environment is changing because the variation introduced leads to an increase in the probability that a variant that can deal with the change. Coprinus cinereus also produces spores by asexual reproduction. These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores is that they generate offspring that are unlikely to be resistant to unfavourable conditions because they are all genetically identical.

Some mushrooms can carry out both asexual and sexual reproduction depending on their environment

what specific actions or events affect climate change in the sahara desert
Answer:
In the future, the Sahara and Sahelian regions could experience more rainfall than today as a result of climate change. Wetter periods, termed African humid periods, occurred in the past and witnessed a mesic landscape in place of today’s hyperarid and semiarid environment. Such large past changes raise the question of whether the near future might hold in store similar environmental transformations, particularly in view of the growing human-induced climate, land-use, and land-cover changes. In the last decades, geoengineering initiatives (in the form of active re-greening projects of the Sahara and Sahel) have been proposed and could have significant effects on the climate of the region. Here, we synthesize the literature on past and projected changes in the hydroclimate of the Sahelian-Saharan region and the associated feedbacks. We further address the current state of knowledge concerning Saharan and Sahelian afforestation projects and their consequences. Our review underscores the importance of vegetation in land-atmosphere-ocean feedback processes and the far-field impacts of northern African ecosystem changes.
