she might have vocal chord paralysis or vocal chord nodules/polyps. it might also be vocal chords being stretched too much and puberty.
Answer:
It would be almost certainly that she has shorter vocal cords
Explanation:
Shorter vocal cords vibrate more quickly in comparison to longer vocal cords, causing a more higher pitched voice.

The water hyacinth is an invasive species that can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity. This situation demonstrates _______. a. how migratory patterns change in response to alterations in an ecosystem b. the effects of symbiosis c. the effects of local evolution or migration on an ecosystem d. how changes in biodiversity impact an ecosystem
1Answer:
The correct answer is - D. how changes in biodiversity impact an ecosystem.
Explanation:
The water hyacinth is an invasive plant species that rapidly grows and creates a thick layer over the water surface in almost every aquatic ecosystem. The growth of the layer of this species causes problems to the environment, ecosystem, humans, and other species.
These aquatic plants reduce the oxygen level and other nutrients from the ecosystem it is introduced and affect the biodiversity by increasing heavy metals and contaminants.
The layer of this plant inhibits photosynthesis that decreases sugar and energy production and blocks the boat and ship movements and economically as well.
Answer:
The correct answer is D

Carbon dioxide and oxygen are linked together in the carbon and oxygen cycle. There are two cellular processes involved in this cycle. What are they called, and what does each process make?
Mark two answers below.
Carbon dioxide is generated by cellular respiration and released into the atmosphere.
Cellular respiration makes oxygen that plants and animals can release into the atmosphere.
Carbon dioxide is a product of photosynthesis that plants release into the atmosphere.
Photosynthesis makes oxygen that plants can release into the atmosphere.
Answer: Photosynthesis makes oxygen that plants can release into the atmosphere.

According to a normal distribution, which organisms are most likely to survive?
Select all that apply.
A. Phenotypes that represent an extreme trait are more likely to survive.
B. Genotypes that represent an extreme trait are more likely to survive.
C. All genotypes have an equal chance of survival.
D. All phenotypes have an equal chance of survival.
Answer:
The organisms that are most likely to survive include:
C. All genotypes have an equal chance of survival.
D. All phenotypes have an equal chance of survival.
Explanation:
The above statements are the correct ones going by the fact that, in any given equal distribution that is normal, the genotypes and phenotypes are have equal chances of survival. Since both are equally distributed among each other.

To measure a population’s baseline genetic state, it must have _____________ to be in Hardy-Weinberg equilibrium.
A) Gene Flow
B) Random Mating
C) Selection
D) Mutations
Answer:
Random mating
hope it helps!
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
To measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).
The Hardy-Weinberg principle state that the genetic variation in a population will remain constant across generations in the absence of different evolutionary forces.The Hardy-Weinberg assumptions include random mating, no mutation, no gene flow, infinite population size, and absence of selection.In consequence, random mating acts to prevent any change in the allele frequencies.In conclusion, to measure a population’s baseline genetic state, it must have random mating to be in Hardy-Weinberg equilibrium (Option B).

Answer:
It increases the production of goods and made our life easier.
Explanation:
The main advantages of technology is that it increases the production of goods and made our life easier while on the other hand, the disadvantages of technology is that it make people lazy and make people socially disconnect from each other. The advantages of technology is that it helps to fulfill the demands of the population and decrease malnutrition problems in the population whereas the disadvantages of technology in food is that it causes many health problems and has low quality. Technology causes many damages to our health as well as our society. It causes pollution in the environment that changes the ecosystem and also leads to the extinction of various species.

Answer:
1. Notochord.
2. Dorsal hollow nerve cord.
3. Pharyngeal slits.
4. Pharyngeal slits.
5. Notochord.
6. Dorsal hollow nerve cord.
Explanation:
A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.
A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.
The four (4) shared anatomical features or characteristics of chordates includes the following;
1. Notochord: found between the digestive tract and nerve cord.
2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.
3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.
4. Pharyngeal slits: in jawed fish this provides support for the jaw.
5. Notochord: provides skeletal support.
6. Dorsal hollow nerve cord: is derived from the ectoderm.

When does DNA replication occur within the cell cycle?
Answer:
Interphase
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Answer:

Explanation:
So you can mark the other person :)
Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.
What is Infrared radiation?All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.
This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

10 pounds of seal for a killer whale to gain one pound (10:1). how many pounds of seal will it have to eat to gain 20 pounds of killer whale?
Answer:
200
Explanation:
20 times 10 is 200 easy
Answer:
200
Explanation:
Multiply 10 by 20 and you'll get 200.
10 pounds = 1 pound gained
? = 20 pound gained
10 : 1
? : 20
1 x 10 = 10
20 x 10 = 200
Hence, the killer whale will have to eat 200 pounds of seal to gain 20 pounds.

Describe the role of photosynthesis and cellular respiration in ecosystems.
Answer:
photosynthesis and cellular respiration allow the carbon and oxygen that organisms consume and produce to be cycled through the ecosystem. They work together so that what is made from one process is used in the other. Without them the ecosystem would run out of carbon dioxide and oxygen, and everything would die.
