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.

To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo™ allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp. thermometers representing the air temperature and body temperature.
1. What is the initial air temperature?
2. What is the initial body temperature?
3. Next to each factor listed below, write "increase," "decrease," or "same" based on how you expect that factor to affect body temperature.
A. Raising air temperature: __same____Sweating: __decrease___.
B. Lowering air temperature: ___increase___Shivering: __increase___.
C. Adding clothing: __increase_____Exercising: ___increase_____.
Answer:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
Explanation:
The question is incomplete, it is necessary to look for a software related to this homework.
Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)
The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.
Then:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.
The effect of different factors on body temperature according to Gizmo:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:
Maintained
D. Set the Exercise level to 70%, then exercising: Increase
When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.

Rocky's class recently got pet turtles. When putting together the habitat, decomposers were added to the soil, as well as some smaller organisms that turtles eat. Some students wanted to get "fake" plants for the terrarium, but Rocky insisted that this would negatively affect the carbon and oxygen cycles.
Which of the following reasons support why Rocky is correct?
Group of answer choices
A) Carbon won't be removed from the air.
B) Photosynthesis won't occur.
C) The turtles won't be able to breathe.
D) All of these are correct.
Will mark as brainliest if correct
Answer:
The correct answer is - D. All of these are correct.
Explanation:
It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.
If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.

In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p).
a. True
b. False
Answer:
True
Explanation:
An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.
The dominant allele is expressed while the recessive allele is not expressed.
The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).
The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.

Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.

4. How should the fossils in the sediment layers of Earth appear if species have evolved over time?
A. All of the layers should contain fossils of simple organisms.
B. All of the layers should contain fossils of complex organisms.
C. The lower layers should contain fossils of more complex organisms.
D. The upper layers should contain fossils of more complex organisms.
Answer:
D the upper layers
Explanation:
at first, lifeforms were simple. they got more complex for a variety of reasons, including to adapt to the changing earth. simple organisms will be lower down for that reason.
The lower layers should contain fossils of more complex organisms. So, the correct option is (C).
What are Fossils?A fossil is defined as the preserved remains, imprint or trace of something that once lived from a previous geological era. Examples of fossils are bones, shells, exoskeletons, fossilized traces of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.
There are four main types of fossils which are formed in different way are conducive to preserving different types of organisms. Fossils are mold fossils, cast fossils, trace fossils and true form fossils.
Fossil layers are fossils that formed in sedimentary rock that formed in layers by depositing and pressing sediments on top of each other.
Thus, the lower layers should contain fossils of more complex organisms. So, the correct option is (C).
