Explain how is it possible to have twins that are not identical
Fraternal (dizygotic) twins come from 2 different fertilized eggs that both grow in the mother's womb. They have different DNA (2 eggs from the mother, 2 sperm from the father) and are not identical, although they often look alike.
Identical (monozygotic) twins come from one fertilized egg that has split in two. These twins share the same DNA and are completely identical.
Identical twins develop from the same egg and sperm,the embryos split and form identical twins ,they are the same sex. But some are fraternal twins, they develop with two diferent sets of sperm and eggs by the same parents. They can be from diferent, this is like having diferent babies at the same time.

How is the cytokinesis of plant cell different from the animal cell during mitosis?
Answer:
a plant cell has a rigid cell wall however an animal cell does not. (more info below)
Explanation:
Because a plant cells are surrounded by the rigid cell wall, it cannot use microfilaments to go through cytokinesis. Instead, it builds a cell plate in the middle of the cell to represent the division. An animal cell does not have this rigid structure, so it forms a cleavage furrow by pinching the cell in the middle with microfilaments. This will successfully divide the cell into two.
hooe this helped!
Answer:
Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes. In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. In plant cells, a cell plate forms along the equator of the parent cell.
Explanation:
What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased?
Answer:
i don't now exactly how to answer this when theres' no food chart however as the vegetation and phytoplankton drastically decrease everything decreases. This is because the producer the bottom of the food chain also known as vegetation is the prime source of energy in every food chain. when there's scarce amounts of producers a domino affect will occur. There will be no food for the first consumers to eat leading their population to decrease and the animals that feed off them will decrease then the animals that feed of them will decrease and so on until the organisms of the food web die out.
Describe step by step, with your own words, the process of replication of a double strand of DNA.
Answer:
replication. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Answer:
B
Explanation:
Answer:
C. Stay calm, watch the child's actions, and try to imagine what the child is feeling
Explanation:
Infants and toddlers are not able to communicate their feelings and emotions effectively. Caregivers need to observe the child's actions and body language to understand what the child is feeling. By staying calm and observant, caregivers can provide the right amount of support to help the child manage stress.

The first model represents the proton and neutron distribution in the nucleus of four helium isotopes. The second image shows the entry for helium in the periodic table. Based on the information in the periodic table, which is the most common isotope of helium?
Answer:
Helium exist as an isotope, its most common isotope is the one that is placed on the periodic table. The helium atom on the periodic table has two electrons, two protons and two neutrons. The proton and the neutron are located inside the nucleus, this means that two protons and two neutrons can be found inside the helium nucleus. Thus, in the pictures given above, the correct picture is the one that contain four particles.

Name two potential pollinations???
Explanation:
male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains.
Insect pollinators include bees, (honey bees, solitary species, bumblebees); pollen wasps (Masarinae); ants; flies including bee flies, hoverflies and mosquitoes; lepidopterans, both butterflies and moths; and flower beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination.
A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process.

Answer:
a. more stable weather conditions --- NE
b. more wheat and less canola grown as crops ---E
c. greater threat to forests from insect pests ----E
d. greater biodiversity of wetland species ----E
e. better agricultural conditions in northern Alberta ----E
f. improved air quality in urban areas-----NE
Explanation:
The climate of Alberto change with the increase in temperature which disturb the weather condition of the region. This increase in temperature decreases the production of wheat crop so more wheat crop is cultivated for fulfilling the needs. This increase in temperature make the environment more suitable for different organisms. The climate is cold during winter so increase in temperature causes condition suitable for agriculture in northern Alberta. Improved air quality in urban areas is not possible due to more production of carbondioxide gas which leads to increase in temperature.

Fish that live in murky water most likely have larger, more developed ___. dorsal fins. olfactory lobes. rosettes. pharyngeal teeth.
Answer:
olfactory lobes
Explanation:
The correct answer would be olfactory lobes.
Murky waters are generally dark, and contains very little (low) light. Fishes that live in murky water need to be specially adapted in order to be able to live in such environment. These adaptations could be in terms of:
A well developed lucidum tapetum, a layer of protein crystals known as guanine which enables them to see through low light and act as a kind of 'night vision'.A well developed olfactory lobe which receives and process information from the olfactory nerve with high efficiency and generally serves to improve the sense of smell.
