Seed plants have pollen
The dust produce male gametes in the wake of entering the female gametophyte. The male gametes intertwine with the egg cell and structure the undeveloped organism inside ovary which develops and frames seeds. The vascular seed plants come up short on dust yet rather creates male gametes in gametangia which are supplanted by the dust in the seed plants.

short term effect if a wild beast migration occurred in savanna grassland
The short-term effect if a migration of wild animals took place in savanna grasslands is higher mortality of adults of migrating species than of resident species.
Why do animals migrate?Several species of birds, mammals, insects and fish migrate from one place to another in search of favorable reproductive and environmental conditions.
Why do animals migrate in Africa?Almost two million animals move across the Serengeti and Mara plains in search of food and water. Facing multiple dangers such as land predators and crocodiles the wildebeest complete an 800 km round trip during the migration.
With this information, we can conclude that The Great Wildebeest Migration is the largest animal migration in the world. Every year, more than 2 million animals (wildebeest, zebra, and gazelle) migrate in a clockwise direction across the ecosystems of the Serengeti (Tanzania) and the Masai Mara (Kenya).

A. The element has 14 neutrons
B.the element has 4 valence electrons
C. The element has 4 electrons
D. The element has 14 protons
For a particular element if only the group number of 14 is known then the element has 4 valence electrons.
What is valence electron?Valence electron is defined as the number of electrons which an atom must lose or gain to attain the nearest noble gas or stable electronic configuration. “Electrons in the outermost shells that are not filled are called valence electrons”.
The valence electrons are termed as the part of the chemical reactions as they contain more energy as compared to the electrons present in inner orbits. Meanwhile, the number of valence electrons which present also helps us to determine a specific element’s chemical properties, such as its valence or valency, the formation of bonds with other elements.
Determination of valence electronOne of the most simple way to find valence electrons is
valance electron = group number (13-17) -10
For group number 14
valence electron = 14-10

As the tide rises and the water flows towards the sea shore, the plants growing at the sea shores wilt. What process is responsible for such effect? A osmosis B diffusion C transpiration D active transport
Answer:
A. Osmosis
Explanation:
When plants are placed into a strong sugar or salt solution water will pass out of the cells by osmosis. As water passes out, the sap vacuole starts to shrink. These cells are no longer firm they are limp. We say that they are flaccid and the plant will wilt.
The process that is responsible for this effect is known as osmosis. Thus, the correct option for this question is A.
What is Osmosis?Osmosis may be defined as the process that significantly involves the movement of solute molecules from a lower concentration to a higher concentration of solution through a semipermeable membrane. It is the net movement of water across a semipermeable membrane.
It is very frequently observed that when plants are exposed to a strong sugar or salt solution, water will eventually be passed out of the cells through the process known as osmosis. As water passes out, the vacuole within the cell starts to shrink. It can be said that they are flaccid and the plant will definitely be in the process of wilting.

Because one original strand of the double-stranded helix is found in each daughter cell, the replication process is called.
Because one original strand of the double-stranded helix is found in each daughter cell, the replication process is called semiconservative replication.
What is semiconservative replication?Before dividing, a cell copies its DNA through the replication process. For instance, before going through mitosis, each parent cell in a human must duplicate all six billion base pairs of its DNA.
Semiconservative replication is the technique used to reproduce DNA. Every strand serves as a model for a fresh double helix. DNA replication as it is now understood, where each double-stranded molecule is made up of one parental strand and one newly polymerized strand.
Every new DNA double helix would be a hybrid after one replication cycle made up of one strand of previously synthesized DNA coupled to another, according to the semiconservative model. The hybrids would then split during the second round of replication, and each strand would partner with a freshly created strand. The remaining half of the new DNA double helices would be entirely new, leaving only half of them to be hybrids. So there would be fewer hybrids and more entirely new double helices after each round of replication.

The highlighted vessels are ________ blood to the heart. The highlighted vessels are ________ blood to the heart. arteries that carry deoxygenated veins that carry oxygenated arteries that carry oxygenated veins that carry deoxygenated
In the circulatory system, arteries take blood from the heart, and veins carry it to the heart. B) The highlighted vessels are veins that carry oxygenated blood to the heart.
What is the circulatory system?The circulatory system is a mechanism that, together with the respiratory system, provides oxygen to the organism and removes carbon dioxide.
The circulatory system is in charge of driving oxygen to all the tissues and cells in the body and taking away carbon dioxide from them.
These gases are in the oxygenated and deoxygenated blood, respectively.
The heart bombs blood through arteries
The oxygenated blood moves forward all tissues and cellsDeoxygenated blood goes to the lungs ⇒ pulmonary artery
This organ also receives blood through veins,
Oxygenated blood enters from the lungs ⇒ pulmonary veinDeoxygenated blood comes from other tissues
So the heart sends blood through arteries and receives blood through veins. Depending on the destiny and origin of this blood, it is oxygenated or deoxygenated.
There are two principal types of circulation,
Lung circulation
1. Moves blood between the heart and the lungs.
2. Deoxygenated blood goes from the heart to the lungs (pulmonary artery)
3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.
4. Carbon dioxide is released by exhalation.
5. Blood absorbs oxygen from small air sacs named alveoli.
6. Oxygenated blood returns to the heart (pulmonary vein).
Systemic circulation
1. Carries blood between the heart and the rest of the body.
2. Oxygenated blood leaves the heart and moves to all the cells in the body (arteries).
3. Deoxygenated blood returns from tissues to the heart (veins).
From the image,
The highlighted vessels are closely related to the lungs. So, according to their position and diametre, we can assume these are either pulmonary veins or arteries.If we consider the statement says that the highlighted vessels move blood TO the heart, we can assume we are talking about veins.
The only veins that move from the lungs to the heart carry oxygenated blood.
According to this reasoning, option B is correct.
The highlighted vessels are veins that carry oxygenated blood to the heart.

Streptomycin is an antibiotic that interferes with the function of the 30s subunit of the prokaryotic ribosome. what is the consequence of treating a bacteria with streptomyci?
Streptomycin is an antibiotic that interferes with the function of the 30s subunit of the prokaryotic ribosome. when it's treated on bacteria it reacts by binding to the site where tRNA typically binds, an anticodon.
Streptomycin, interferes with ribosomal activities and inhibits bacterial protein synthesis in vitro. Streptomycin can fit into the binding site for anticodons and interfere with the binding site for tRNA derivatives due to the structural similarities between it and the anticodon.
For instance, it prevents polypeptide synthesis triggered by either synthesised polynucleotides or natural mRNA3-5, leading to significant genetic code misinterpretation in the latter scenario. The medication also causes polysomes to break down and releases fMet-tRNA from interacting with the 70S ribosome.
