How true can ultrasound results be when telling an embryo's stage?
Ultrasound results are typically very accurate in determining an embryo's stage during pregnancy. This is because ultrasound technology provides detailed images of the developing embryo, allowing healthcare professionals to assess its growth and development with precision. However, there may be some margin of error, and it is important to follow up with additional ultrasounds to track the embryo's progress.
True or false human sperm and egg cells have 23 chromosomes?
True. Sperm and egg cells are gametes, and thus are necessarily haploid. These haploid gametes were created through the process of meiosis. When the two fuse to create an embryo, the new embryo will then have 46 chromosomes, the full number for a human. The embryo will receive one copy of each chromosome from each parent. If sperm and egg cells were to have the full set of 46 chromosomes, with both copies of each chromosome from each parent, then when they fused the embryo would have 92 chromosomes total. And the progeny of that embryo would have an even higher number of chromosomes. Having haploid gametes is necessary to maintain the stability of the species.
What are The first two leaves on a bean plant are called?
The first two leaves on a bean plant are called cotyledon leaves. These leaves are part of the seed embryo and are different in shape and function compared to the plant's true leaves which will develop later.
How many ribs do a human have on the front of their body?
Humans normally have 14 true ribs on the front of their bodies, and 10 false ribs. True ribs are attached directly to the sternum (breastbone) at the front of the body, and the false ribs are not.
When a tRNA anticodon bind to an mRNA codon the amino acid detaches from the tRNA molecule and attaches to the end of a growing protein chain?
Yes, when a tRNA anticodon binds to an mRNA codon during translation, the amino acid that was carried by the tRNA detaches from the tRNA molecule and becomes part of a growing polypeptide chain. This process ensures that the protein is built in the correct sequence dictated by the mRNA codons.
Does the sperm start to fertalize inside the fallopian tube?
No. Fallopian tubes exist only in women. Sperm is produced only by men.
Why is the yolk sac of a chick embryo smaller than a human embryo?
No , reverse is true .
Is it true that some women grow another fallopian tube?
No
Is it true that a woman can GROW a new fallopian tube after a ligation?
false
What attaches the shoulder to the sternum?
The clavicle. This bone is normally not consideredto be part of the shoulder an instead a part of the thorax, which is also true. The reason it is part of the shoulder is that it joint part of the scapula to form the soked of the glenohumeral joint.
Is the beginning of the development of an embryo into a new plant is known as germination?
true
True or false personhood is legally defined as an eight-cell embryo?
False
Is it true that the embryo uses its stored food to begin to grow?
Yes, that is true. You can see this stored food in bird eggs. It is what we call the yolk. In mammals, there is only a small amount until the embryo makes a connection with the mother via the placenta.
When you sort data are duplicates normally included true or false?
true
Is it true that in ancient Greece competitors normally played naked?
true
What is the function of a plumule in a seed?
The plumule is the bud of a young plant; the portion of the plant embryo giving rise to the first true leaves. Without the plumule you'd have no leaves.
If the placenta were to detach from the mothers uterus early would the embryo stop receiving food and oxygen?
True
