AnimalsBirdsPlantsdraw a line from each hormone in list A to the correct information in list B
Answer:
The correct answer would be -
FSH - used as fertility drugs to makes egg mature.
LS - stimulates the release of eggs.
Oestrogen - causes the lining of the womb to break down.
Explanation:
FSH is a hormone released from the pituitary gland and is the abbreviation of Follicle-stimulating hormone which controls the menstrual cycle and growth of eggs in ovaries. It is also used as a fertility drug that promotes the growth of eggs to mature it.
LS or Luteinising hormone is the hormone that is released from the pituitary gland and promotes the surge of the release of eggs.
Oestrogen is the hormone that helps females during puberty during the menstrual cycle to breakdown the lining of the womb.

Some seeds are endosed in a sweet, fleshy fruit. How would damage to the vascular tissue (Xylem and pholem, affect the developing fruit? A.Damaged vascular tissue would cause the developing fruit to accel in growth.
B . It would not affect the developing frut but it would affect the flower.
C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.
D.The xylem and pholem are not parts of a plant and therefore would not affect anything.
Answer:
C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.
Explanation:
If the vascular tissues such as xylem and phloem are damaged, the fruit does not completely develop because the food that is produced in the leaves does not reach to the seed. The xylem helps in the transportation of water from the soil that is necessary for making of food during the process of photosynthesis so damaged xylem will not produced food and no food will be transported from leaves to seeds and if some food is produced by the leaves the phloem does not transport it to the seeds.
How do scientists use fossils to study climate?
PLS HELP
Answer:
Many small organisms can be preserved within these layers of sediment through time. The changing abundances of these fossils through time can tell us whether a change in the environment or climate was gradual or abrupt. Studying fossil pollen and other fossils helps scientists to learn more about climate change.

B. raspberry jam
A. benedict's solution
B. benedict's solution
E. V ground turkey
C. lodine
C. plain oatmeal
D. sudan IV
A honey
E. bluret reagent
Answer:
raspberry jam - benedict's solution
honey - benedict's solution
ground turkey - biuret reagent
oatmeal - iodine
Explanation:
Benedict's test is a test used to confirm simple carbohydrates. it helps in identifying reducing sugars that have free ketone or aldehyde functional groups. Raspberry jam has mainly carbohydrates that can be tested by this indicator.
An iodine test is for the determination of starch which is a non-reducing sugar such as oatmeal
Sudan IV (C24H20N4O) is used for the presence of staining of lipids, triglycerides and lipoproteins. There is no food item given that has a proper amount of fat or lipid
Beuret reagent is a protein testing reagent that shows the presence of the protein. Ground turkey has a huge amount of protein that can be indicated by this

(Punnett square and chart attached)
Explanation:
1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.
2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.
3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.
4. The mother has a dominant allele and a recessive allele.
5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.
6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

Which statement about oogenesis is correct?
A. Diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body.
B. Two diploid secondary oocytes undergo meiosis II to form four haploid ootid cells.
C. Haploid secondary oocytes undergo meiosis I to form a haploid ootid cell and a polar body.
D. Haploid secondary oocytes undergo meiosis II to form a diploid ootid cell.
The statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
What is Meiosis?Meiosis may be defined as a type of cell division in which each parental cell is divided into four daughter cells. These daughter cells are genetically unique to the parental cells and are haploid in nature. Germ cells (gamete cells) are typically divided through this mode of cell division.
Oogenesis may be characterized as the process of female gamete formation including the formation of an oocyte from an oogonium followed by meiotic division. During the process of oogenesis, a haploid ootid cell and a polar body are formed with the help of meiotic division.
Therefore, the statement which is true about oogenesis is that the diploid secondary oocytes undergo meiosis II to form a haploid ootid cell and a polar body. Thus, the correct option for this question is A.
