Common Ancestor
A. Earthworm
B. Amoeba
C. Sponge
D. Salmon
Answer:
I'm thinking an earthworm.
A leech is most likely to be closely related to Earthworms, as they both have segmented bodies and are multicellular organisms. The option is A.
What is leech?A leech is a multicellular organism with a segmented body and does not have jaws or limbs. The terms to consider in this question are: - Multicellular - Segmented Body - Common Ancestor Based on these characteristics, the leech is most closely related to: Earthworm.
Both leeches and earthworms are multicellular organisms with segmented bodies and share a common ancestor. They belong to the phylum Annelida, which consists of segmented worms.
The other options listed (Amoeba, Sponge, Salmon, Lizard, Kangaroo, Cat, Placental, Hair, Jaws, Unicellular, Common Ancestor) do not share these characteristics with leeches.

In the human body, the blood stream transports water and nutrients throughout the body. Which type of tissue serves a similar function in plants?
1-ground
2-connective
3-vascular
4-dermal
In the human body, the blood stream transports water and nutrients throughout the body, and the type of tissue that serves a similar function in plants is the vascular tissue that is in option 3.
What is the importance of vascular tissue in plants?Vascular tissue in plants serves many functions, including distributing water and nutrients throughout the plant and allowing the plant to grow and maintain its health. Through the vascular tissues, plants transport the products of photosynthesis to all parts of the plant and absorb water and nutrients from the soil.
Hence, in the human body, the blood stream transports water and nutrients throughout the body, and the type of tissue that serves a similar function in plants is the vascular tissue that is in option 3.

Please correct me if I am wrong for the third one
Answer:
1. Hypotonic
2.Isotonic
3.Hypertonic
Explanation:
Number 1 is hypo tonic because solute is going into the cell. The cell is getting bigger and expanding. You can think of Hypotonic as getting bigger by using Hypo which can be Hippo. Hippos grow bigger over time.
Number 2 is Isotonic. The water is going in and out at the same rate. Therefore, nothing really changes here.
Number 3 is Hypertonic because the cell has shrunk.

Topic is about blood types.
Answer:h
Explanation:
Choose the correct statements 1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. 3cross-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. 4.Self-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explain how vaccination protects a child against a viral disease.
Answer:
Explanation:
It doesn’t is actually makes u sick sometimes but if u agree then vaccinations mean when only a bit of the pathogen is ingested into to u for ur body to become immune and so if u get the disease yours body has already made antibodies which contain a special format in which they break down the pathogen faster.and the pathogen will be broken down quickly as the process is faster when your body already contains the code against it.
What causes the light to refract as it
passes from air to water?
Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction
