D. They lack nuclei and have no organelles!
1. According to the law of conservation of mass, in an isolated system, mass is neither created nor destructed by the physical conversions or chemical reactions. It is on the basis of the law of conservation of mass that in a chemical reaction, the mass of the products must be equivalent to the mass of the reactants.
2. A chemical equation tells us about the phenomenon of conservation of mass, that is, atoms are neither created nor destroyed at the time of a chemical reaction. A balanced chemical equation tells us that which substances are the products and what substances are the reactants, and what proportion of each substance are taking part, as well as their association with each other, and the steps that take place at the time of a reaction.
Answer:
1.Ovulation
2.Implantation
3.Zygote
4.Fetus
5.Conception
6.Embryo
7.Trimesters
Explanation:
Implantation is a procedure where a developing embryo, moving as a blastocyst through an uterus, reaches the uterine wall and stays connected to it until birth.
embryo is an unborn posterity of a warm blooded creature, specifically an unborn human infant over about two months after origination.
Zygote is a diploid cell coming about because of the combination of two haploid gametes,
Trimester is a time of a quarter of a year, particularly as a division of the length of pregnancy.
Conceiving is the action of conceiving a child or of a child being conceived. Conception is the time when sperm travels up through the vagina, into the uterus, and fertilizes an egg found in the Fallopian tube. Conception — and ultimately, pregnancy — can involve a surprisingly complicated series of steps
In females , implantation is the phase of pregnancy at which the incipient organism holds fast to the mass of the uterus. At this phase of pre-birth improvement, the conceptus is known as a blastocyst. It is by this grip the incipient organism gets oxygen and supplements from the mother to have the option to develop.
Ovulation is the name of the procedure that happens for the most part once in each menstrual cycle when hormone changes trigger an ovary to discharge an egg. You can possibly end up pregnant if a sperm prepares an egg. Ovulation as a rule happens 12 to 16 days before your next period begins. The eggs are contained in your ovaries.
Fetus: A living being in the beginning times of development and separation, from preparation to the start of the third month of pregnancy (in people). After that point in time, an incipient organism is known as a baby.
C) they are both places where ATP is produced.
Animal cells don’t have thylakoids.
Animal cells do not contain chloroplasts or chlorophyll.
Glycolysis occurs in the cytoplasm.
Answer:
more worms are need for the soil to make it healthy
Explanation:
Worms help to increase the amount of air and water that gets into the soil. They break down organic matter, like leaves and grass into things that plants can use. When they eat, they leave behind castings that are a very valuable type of fertilizer. Earthworms are like free farm help.
