Answer:
Epidermis (A)
Explanation:
Correct on Edgd
Ophrys sphegodes, the early spider orchid, has flowers with yellow-green sepals and petals and one highly modified, velvety brown central petal at the base of the flower. There is single male anther is found at the tip of the column. The stigma is on the underside of the column just below the anther.
Required:
a. Is the flower complete or incomplete?
b. Is the flower perfect or imperfect?
c. Is the flower radially or bilaterally symmetrical?
Answer and Explanation:
a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.
b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.
c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

what are the different between plant and animal cell.
Answer: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.

Fresh steak is said to have both negative and positive redox potential. Discuss how the redox potential affects the microbial ecology of the food
Answer:
Increases redox potential decreases microbial growth inside food.
Explanation:
The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.

Which class of Lever is being described if you are standing on tiptoes and if: The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. The Load is your body weight which is in the middle of this lever. The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body.
Answer:
Second class lever
Explanation:
A second class lever is when the resistance ( load/weight ) is placed in between the axis ( Fulcrum which is formed by the metatarsal and Phalanges ) and the force ( Achilles tendon ) that is applied to the lever. hence the class of lever being described is a second class lever
There are three classes of lever ( 1st class, 2nd class and third class ) but The most common lever found in Humans are the 3rd class levers. but standing on tiptoes by an individual is a perfect example of a 2nd class lever found in a Human.
The Load being the body weight being and in the middle of this lever is
referred to a the second class lever.
The second class lever has the load in between the effort (force) and the
fulcrum. A common example is the wheelbarrow which has the load in the
middle.
In this scenario, the load which is the body is between the
effort(gastrocnemius and soleus muscles) and the fulcrum is the phalanges
which is a characteristic of a second class lever.

Which numbers identify the organelles that are present in BOTH plant and animal cells?
Answer: answer is A. Because both plants and animals have plasma membranes, cytoplasm, and mitochondria.
Further Explanation
Cell organelles are components of the cell and life. Cell organelles are the most important part of cells that function to regulate the life processes in cells. Cell organelles are in a part called the cytoplasm. Cell organelles consist of several parts, each of which has a different function but functions as a system that supports the life processes that occur in cells.
Animal Cell Organelles
Animal Cell Organelles are forms of eukaryotic cells that form body tissues and then form organs.
Animal cell organelles consist of:

Explanation:
If u and y are two variables such that
du
= 4v - 3. and u = 5 when v = 2,
du/dv
find u in terms of v.
Answer:
5
Explanation:
The value of u is 5 in term of v by putting the value o v which is 2 in the formula that is du = 4v - 3. Putting the value of v = 2 we get, du = 4(2) - 3. --- du = 8 - 3. ---- du = 5. we are able to solve the question due to the presence of v value. If the v value is not present then we can't find the value of u in term of v. So we can conclude that the value of u in term of v is 5 if we put the value of v in the formula.

According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.
