The amount of matter is conserved when a substance changes form. When matter changes drastically it is not actually destroyed. This can be tested by weighing all the materials involved in an experiment before starting it, and again after the

Q - Natural active immunity
Question:
In your opinion, which immunity is the best? Why?
Anyone plz help this question...?
Answers
Answer:
The correct answer would be - natural active immunity.
Explanation:
Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.
If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.
In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.

Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

B. point (-1,-3)
Oc.
point (-3,-5)
O
D. point (-3,-1)
Answers
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

Bleeding from artery is more dangerous than that from vein, why?
Answers
Answer:
Due to the high pressure arteries hold and it is difficult to control.
Explanation:
Consider most of the arteries (minus the pulmonary arteries) have a thicker layer (lumen) that basically resists the ejection of blood from the heart. Arteries hold oxygenated blood to the vital organs (the heart itself throught he coronary arteries, the brain that needs EXCLUSIVE oxygenated blood, and lungs). Contrasted to a bleeding vein, bleeding from an artery tends to go faster, which increases the risk of hemorrhage and death.

We have 2 genes here, so we are coding for 2
different traits, AKA 2 distinct and separate
phenotypes
However, both phenotypes are present in each
offspring cat.
So, for example we could have a hairy, sink-
loving cat (like one of the parents) or a
hairless, sink-hating cat (like the other
parent). What are the other possibilities for
phenotype?
Make sure to include both traits (hair/hairless
and feelings about sinks) for each possible

1. Snapdragons can be red (RR), white (WW), or pink (RW). Cross a red snapdragon with a pink snapdragon. Give the genotype and phenotype percentages.
Answers
Answer:
RR (hom0zygous dominant) - 50%
RW (heterozygous) - 50%
Red flower - 50 %
Pink flower - 50%
Explanation:
To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.
R R
R RR RR
W RW RW
50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.
This Venn diagram is being used to compare the characteristics of nonvascular and vascular plants.
Which characteristic is shared by the two plants, and can therefore be placed in the overlapping section?
have roots
perform photosynthesis
have xylem and phloem
produce seeds
Answers
Answer:
perform photosynthesis
The specific xylem and phloem tissues that vascular plants (tracheophytes) have for supporting and conducting water and food, respectively, set them apart from nonvascular bryophytes.Thus, option B is correct.
What best defines about nonvascular and vascular plants?The existence of chloroplasts and the green pigment chlorophyll, which enable plants to carry out photosynthesis, is the fundamental similarity between these two plant groupings. Due to their capacity to manufacture their own food, plants are now the main contributors to the ecosystem's production.
Tracheophytes are another name for vascular plants. Pteridophytes, gymnosperms, and angiosperms are among them.Nonvascular plants lack the specialized vascular system required to transmit water and nutrients. Examples of simple structures that are specialized for doing transportation are those found in algae and bryophytes.
Therefore, perform photosynthesis characteristic is shared by the two plants.
