genetic engineering might allow parent to 'design' their children before birth are you in favor of this? why or why not?
Answer:
I think it is quite an interesting idea to allow parents to 'design' their children before birth. Because some people have preferences and those preferences are taken very seriously. I wouldn't want to have a baby boy, I would want a baby girl. Although, this could be a waste of money and time because this might be one of the things that are better not to be fixed even if it isn't broken. But, this can also be good, if you desperately need a child with specific features, this can help. Even if I can't seem to find a reason where a child is supposed to have specific features.
Explanation:
The alteration of the natural gene by the tools is called genetic engineering. The application of genetic engineering is to make transgenic animals that give protein-rich products and transgenic plants which are disease-free.
The idea of genetic engineering is quite subjective. some people find it right and some find it wrong. In order to evolve biological science, genetic engineering is important but ethically and morally genetic engineering is not good as we altering nature's work.
Genetic engineering allows a parent to check the genetic disease of the child and help them to cure it but it is ethically wrong if they used it to find the sexual gender of the child.
Hence, genetic engineering is wrong in a limited way.

These are born in cones and are not visible until maturity.
There are several characteristics of Gymnosperms. They are:
1. They are autotrophic, photosynthetic plants which tend to conserve water.
2. They have vascular system which includes roots, xylem, and phloem that is used for the transportation of water and nutrients.
3. The ovules and seeds of gymnosperms develop on the scales of cones which is in enclosed chambers called ovaries.
4. They are older than angiosperms on the basis of evolution.
They are divided into four classes like

How are rabbits adapted? Write in short.
Answer:
The rabbit's eyes are set high on the head, and is complimented with a weak but very flexible neck which allows the animal to rotate its head. These adaptations let the rabbit have a greater field of vision, which helps in spotting food as well as predators. They also have strong legs that are made for running.

Explain how an animal grows?
Answer:
big liitle fat
Explanation:
Answer:
The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. These new, or daughter, cells are often similar in size to the old, or parent, cells.

syngamy and triple fusion difference
mark me as brainlest
Answer:
Üçlü füzyonda, üçüncü bir sperm çekirdeği, embriyo kesesindeki merkezi hücre ile birleşerek endospermi üretir. Eşleşme ve üçlü füzyon arasındaki temel fark, eşleşmenin bir tür üretici döllenme olduğu, üçlü birleşme ise bir tür bitkisel döllenmedir .İyi Çalışmalar..
Answer:
Syngamy: Syngamy refers to the fusion of gametes in fertilization.
Triple Fusion: Triple fusion refers to the fusion of a sperm cell with the two polar nuclei during the double fertilization in angiosperms.
Type of Fusion
Syngamy: In syngamy, a male gamete fuses with a female gamete.
Triple Fusion: In triple fusion, a male gamete fuses with the central cell.
Result
Syngamy: Syngamy produces the zygote that develops into the embryo.
Triple fusion: Triple fusion produces the endosperm cell that develops into the endosperm.
Ploidy
PloidySyngamy: The result of the syngamy is diploid.
Triple Fusion: The result of the triple fusion is triploid.
Type of Gametes
Type of GametesSyngamy: Both male and female gametes are involved in the syngamy.
Triple Fusion: Only male gametes are involved in the triple fusion.
Type of Fertilization
Syngamy: Syngamy is a generative fertilization.
Triple Fusion: Triple fusion is a vegetative fertilization.
Occurrence
OccurrenceSyngamy: Syngamy occurs in animals and plants.
Triple Fusion: Triple fusion occurs in angiosperms.
Conclusion
Syngamy and triple fusion are two types of events in the sexual reproduction of plants. Syngamy is the fusion of male and female gamete, producing the zygote. Triple fusion is the fusion of a male gamete with the central cell of the female gametophyte, producing the endosperm. The main difference between syngamy and triple fusion is the type of fusion of cells in each event.

Design your own scenario related to Bacteria or Viruses. Identify the independent and dependent variables.
Answer:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration for example, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
Explanation:
An independent variable is a variable that represents a quantity that the scientist modifies in an experiment. A dependent variable represents a quantity whose value depends on how the independent variable is modified. This is the variable being studied and measured.
So, an example of this applied to bacteria or viruses could be:
An experiment where an antibiotic is tested against bacteria. The antibiotic can vary in its concentration, different amounts are applied to a sample of bacteria to see if it is affected by the action of the antibiotic and if so, in what concentration. So, the independent variable is the concentration of antibiotic while the dependent variable is the survival (or not) of the bacteria.
To complete the experiment, an antibiotic whose effect is already known can be used as a positive control. That is, it is already known to kill the bacteria. And as a negative control you can simply use water, which has no effect and is known not to kill the bacteria. In this way, we validate the results and make sure that there is not something else that is affecting the bacteria and that only the antibiotic being studied has an influence.

Answer:
A. Mid-ocean ridge. I'm not sure if I'm right.
The place where the new volcanoes are less likely to be seen is mid-ocean ridge. The correct option is A.
What is volcano?A volcano is a crack in the crust of a planet, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber beneath the surface.
Volcanoes are most commonly found where tectonic plates are diverging or converging on Earth, and the majority are found underwater.
Although Australia is the only continent with no active volcanoes, it does have one of the world's largest extinct volcanoes, the Tweed Volcano.
Volcanism is directly related to plate tectonics theory. Volcanoes are only found at specific types of plate boundaries, and only rarely in the middle of ocean plates.
Thus, the correct option is A.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

B. The amounts of sun, water, and nutrients affect the
growth of a plant
C. Parents with red hair have a child with red hair
D. A red snapdragon flower is crossed with a white
snapdragon flower to produce a pink snapdragon flower.
Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.
