Write your question here (Keep it simple and clear to get the best answer) what name iz give to the female part of the flower?
Answer:
The female part of the flower is called gynoecium or pistil
Explanation:
The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.
The stigma is a sticky knob-like structure located at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.
The style is a long long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule
The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules. After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.
Three samples were taken and were put in three test tubes each named as A,B and C. In A, milk was added, B had meat pieces and C had crushed potatoes in it. Observe the names of tests written above each test tube and write (for all test tubes) • Material Required • The Procedure • Expected End Results • Conclusions • Safety Measures (if any) If you find any negative result. Explain why it is so?
Answer:
A is the test of protein, B is the test for fat and C is the test for starch
Explanation:
For A, the materials required are;

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light

In a small population of alpine foxes, you observe increased ear length over a 10-year period. Can you conclude that increase in ear length is advantageous in this population
Answer:
No, I can't conclude that because there are several factors that influence the expression of a trait (for example, gene drift)
Explanation:
There are several factors that affect the genetic variation of a phenotypic trait in populations with small sizes. Genetic drift is an important evolutionary mechanism by which allele frequencies change in populations, and it is well known that the effects of genetic drift are most pronounced in small populations. Moreover, gene flow -or migration- is an evolutionary factor (stronger in small populations) that is also potentially capable of changing allele frequencies and thus contribute to the overall genetic variation of a phenotypic trait. Finally, environmental factors (for example, abiotic and biotic stresses) may also be associated with the variation of a quantitative trait such as, in this case, ear length.
How is mitosis different from binary fission?

A. Cell A
B. Cell B
C. Cell C
The cell that would have the most trouble maintaining homeostasis is cell A. The correct option is a.
What is homeostasis?Any self-regulating process, such as homeostasis, helps an organism retain stability while responding to environmental factors that are favorable for its survival. If homeostasis is effective, life continues; if it is not, the organism perishes or suffers a catastrophe.
There are three cells in the given which are of different sizes' cell a is 1 cm cell 2 is 2 cm and cell 3 is 3 cm from each side.
Cell A would have the most towel in maintaining homeostasis, says because it is small and growing is one of the terms needed for maintaining homeostasis. If the organism is small it would have difficulty, then the organism is big it would easily maintain the homeostasis of his body.
Therefore, the correct option is a, cell A.

Which best describes pitch?
the amount of time taken for a longitudinal wave to produce one cycle the number of cycles per second perceived by the human ear the amplitude of a wave when the natural frequency is matched the distance between two corresponding parts of a transverse wave
The answer is B. the number of cycles per second perceived by the human ear
I got this question right :)
The pitch is the number of cycles per second perceived by the human ear. The correct option is B.
What is pitch?The ability to assess sounds as "higher" and "lower" in the sense associated with musical melodies is known as pitch.
Pitch is a perceptual feature of sounds that allows their ordering on a frequency-related scale.
Pitch in physics refers to a sound wave's specific frequency, which is expressed in Hertz (Hz).
There are two ways in which these frequencies match musical notes. high tone: A high pitch is one that vibrates at a high frequency.
Pitch is a perceptual quantity that depends on the listener, but frequency is a physical quantity that indicates the number of vibrations per second. In truth, our ears perceive pitch rather than frequency.
The pitch is how many cycles per second the human ear can detect.
Thus, the correct option is B.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
A microscopic image of staphylococcus aureus is shown.

What would be a probable explanation for why there are many endemic plants and birds in New Zealand, but no native mammals?
Answer:
Due to isolated before mammals evolve.
Explanation:
There are many endemic plants and birds in New Zealand, but no native mammals because New Zealand is an island which isolated from Gondwana which is a supercontinent about 85 million years ago. Before mammals evolved, the New Zealand splits and go away from the Gondwana. So due to water only those mammals that can swim or fly colonized in New Zealand but not the land living mammals.
