A garden contains 40 flowers, 30 of which are red. What is the frequency of red flowers?
Answer:
0.75
Explanation:
a frequency of 1.0 occurs when all the flowers are red
A garden that contains 40 flowers, 30 of which are red. Then, the frequency of red flowers is 75% of 1:3.
What is Frequency?Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as the temporal frequency for clarity, and is distinct from angular frequency. Frequency is usually measured in hertz (Hz) which is equal to one event per second.
Gene frequency is the fraction or percentage of a population which carries a particular allele at a particular gene locus. In this case, a garden has 40 flowers, in which 30 are red.
Therefore, the frequency of red flowers = Number of red flowers/ Total number of flowers
The frequency of red flowers = 30/ 40 = 75% or 1/3

What are some ways that natural selection equips organisms for survival in their environment?
Answer:
Well organisms who have traits that are beneficial to them and would make them live long enough to usually reproduce, it would become an adaptive trait. That organism who has that trait will most likely live the longest and reproducing which will pass down their traits. Other same type of organisms who don’t have that trait will most likely die quicker then those who do and they won’t be able to pass on their genes which will lead to the natrual selection being very few of those types. If your born with a non useful trait, you jsut pass it down, you can’t just have the ones that benefit you unless yoru parents have it. This is why at the ”end” there will be more with useful traits and barley any with non.

Describe what it means when we say that DNA replication is semi-conservative:
Answer: Semi-conservative replication means that during DNA replication, the two strands of nucleotides separate. Both strands then form the template for free nucleotides to bind to to create the two identical daughter strands. Hence each daughter strand has half of the DNA from the original strand and half newly-formed DNA. brainliest

How does the extinction of species affect humans?
A. Extinction generates new sources of medicine.
B. Extinction upsets the natural cycling of nutrients,
C. Extinction helps keep air and water clean.
D. Extinction makes the environment more pleasant.
Answer:
B. Extinction upsets the natural cycling of nutrients
The extinction of species affect humans as extinction upsets the natural cycling of nutrients. Therefore, option (B) is correct.
What do you mean by extinction of species?Extinction is the end of a sort of life form or of a gathering of sorts, normally an animal categories. The snapshot of annihilation is for the most part viewed as the passing of the last person of the species, albeit the ability to raise and recuperate.
As species go terminated, they are removed from the established pecking order. The animals that ate the species that has gone extinct must find new food or die. Other animal or plant populations could suffer as a result.
Habitat loss and degradation (primarily deforestation), overexploitation (hunting and overfishing), invasive species, climate change, and nitrogen pollution are the main modern causes of extinction.

How is a typhoon formed?
Answer:
A typhoon forms when winds blow into areas of the ocean where the water is warm. These winds collect moisture and rise, while colder air moves in below. This creates pressure, which causes the winds to move very quickly. The winds rotate, or spin, around a center called an eye.
Explanation:
Answer:
Compared to tropical cyclone, we have a few main requirements for typhoon development:
1. sufficiently warm sea surface temperatures,
2. Atmospheric instability,
3. High humidity in the lower to middle levels of the troposphere,
4. Enough Coriolis effect to develop a low pressure center,
5. pre-existing low level focus or disturbance, and
6. low vertical wind shear.

The diagram below shows the first four steps of meiosis.what's is happening in step labeled c?
Part a:the diagram below shows a cross section of a cell membrane. Describe the basic structure of the cell membrane.
Phospholipid bilayers are the basic building blocks of the membrane.
They form a stable boundary between two water-containing compartments. In a plasma membrane, these two compartments are the interior and exterior of the cell.
A cell membrane is a sheet of double membrane that mainly consists of lipids. These membranes are semi-permeable, meaning that some molecules are able to pass through the lipids bilayer, while others are unable to.
Small hydrophobic molecules (e.g., oxygen or carbon dioxide) pass through membranes rapidly. Similarly, small polar molecules (i.e., water and ethanol) pass through membranes more slowly.

why dont plants photosynthesise in the dark
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.

Produces and secretes bile. Alternates contraction and relaxation of smooth muscles along the length of the GI tract. Largest salivary gland anterior to each ear. Another term for chewing. Covers dentin and glues the teeth to the periodontal ligament. Secrete hydrochloric acid in the stomach. Vessels absorbing and transporting fatty acids and monoglycerides. Pancreatic juice enters this region of the small intestine. Has both endocrine and exocrine functions. Finger-like extensions in the epithelial cell membrane.
Answer:
The correct answer would be -
1. liver 2. peristasis 3. parotid 4. mastication 5. cemuntum 6. parietal cell 7. Lacteal 8. duodenum 9. Pancreas 10. microvilli
Explanation:
The liver is the gland or the organ that is responsible for the production of bile and secreted into the duodenum during digestion.
Peristalsis is the movement that helps in forwarding propulsion of food/bolus
The parotid is a gland that produces and secrets saliva for moistening the food and digesting carbohydrates.
Mastication is a process that helps in crushing and breaking the food into smaller pieces.
Cementum is a substance that covers the root of the teeth and glues the teeth to the periodontal ligament.
Parietal cells secrete hydrochloric acid to remove the pathogens and activating pepsinogen.
Lacteal vessels absorb fatty acids and transport them
Duodenum is the region where pancreatic juice and bile is secreted.
The pancreas is an organ and gland that acts as exocrine and endocrine gland
Microvilli are the projection look like fingers in the epithelial cell membrane.
