Answer:
Over millions of year some stars blow up. Then the star dust from those gather and create new stars.
Explanation:
During the time of the dinosaurs, the constellations are not as clear as compared to the present time. This is also because stardust was assembled together to create new stars.
What do you mean by Astronomers?An Astronomer may be defined as a scientist in the field of astronomy who concentrates their investigations on a distinctive question or field outside the scope of Earth.
Constellations are referred to a group of stars that construct a recognizable imprint in the sky. This process helps scientists to locate objects in the sky.
Therefore, during the time of the dinosaurs, the constellations are not as clear as compared to the present time. This is also because stardust was assembled together to create new stars.

What type of genetic material does a Blue whale contain?
Answer:
The blue whale is very genetically diverse. There are four subspecies of blue whale: B. musculus musculus, B. musculus intermedia, B. musculus indica, and B. musculus brevicauda. Very little is known about the genetic differences between these species besides appearance and weight. The subspecies don’t usually mix because of location.
In the 19th and early 20th centuries, almost all of the blue whales were killed for their baleen plates. They are now increasing in population, and scientists would like to try to see what they can do to continue to increase the population.

For what type of organism is the carrying capacity shown?
Answer:
I'm pretty sure it's white tailed deer, since that's what the graph is describing and showing the carrying capacity for.
White tailed deer has the carrying capacity in the graph.
What is carrying capacity ?The carrying capacity of any organism can be defined as the maximum population size of the species in a sustainable environment indefinitely up to the limit no further growth.
Carrying means to support and Capacity refers to the ability to reproduce the maximum output, when population reaches the carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly based on concept of sustainability, environmental imbalances and Global warming is also causative agent, eradication of poverty and provision of the traditions, practices are also enhance the carrying capacity importance.

Analyze how osmosis affects the size of the cell when placed in either an isotonic, hypotonic or hypertonic solution.
Discuss the direction of the movement of water across the cell membrane for each situation above and how this affects cell size.
Explanation:
Osmosis is defined as the movement of water from a LOW concentration of solute to a HIGH concentration of solute.
Isotonic means that both the solution (environment of the cell) and the inside of the cell have equal concentrations. Now, it is important to know that even though they may have similar concentrations, there may be different solutes inside or outside of the cell.
Hypertonic is when one solution (either the inside of the cell or the outside) has a higher concentration of a certain solute
Hypotonic is the solution that has the less concentration of a certain solute.
If the inside of the cell has more solute than the outside, then the water will move inside the cell, make it bigger, and eventually make it burst.
If the outside of the cell has a higher concentration of a solute, the water inside the cell will move out of the cell and go to the environment. This will cause the cell to shrink in size.
If both the outside and inside of the cell have the same solutes at the same concentration, then the two are said to be isotonic, and the cell will keep its normal shape.
What type of membrane protein has a
straight pathway for molecules to move?
A. Channel protein
B. Carrier protein
C. Receptor protein
D. Glycoprotein
Answer: C
This membrane protein is a receptor protein. Polytopic membranes cross the membrane for the molecules a couple times. The answer is C.
Hope it helps!
The type of membrane protein that has a straight pathway : ( C ) Receptor protein
Receptor protein binds ligands molecules outside a cell after which it changes its conformation and transmits signal from the molecules through molecular switches into the cell ( via the signal pathways of the cell ).
The process of binding ligand molecules, transmitting signals into the signal pathways of the cell follows a straight pathway for the movement of molecules.
Hence we can conclude that the type of membrane protein that has a straight pathway for molecules to move is Receptor protein.

how is Lysosomes are formed
Answer:
lysosome formationLysosomes form by budding off from the membrane of the trans-Golgi network. Macromolecules (i.e., food particles) are absorbed into the cell in vesicles formed by endocytosis. The vesicles fuse with lysosomes, which then break down the macromolecules using hydrolytic enzymes.

What forms at a convergent plate boundary?
Answer: Usually, one of the converging plates will move beneath the other, a process known as subduction.
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

Male pine cones contain:
soft scales
a sticky fluid
sperm tubes
pollen sacs
Answer:
Male cones are a lot smaller than female cones and their scales aren't as open. Each scale in a male cone contains the pollen that can spread to a female cone to make a seed.
Explanation:
I don't know what you are asking but that is my answer.....be more specific.
Answer:
Male pine cones have a sticky fluid, sperm tubes, and pollen sacs.
Explanation:
Both male and female pine cones have sperm tubes, but only females have soft scales. Male cones have rough scales that let the pollen in and out of it. Although female cones soft scales, they still allow pollen to enter into the cones. The pollen that goes into the female pine cone never gets out, though.
describe how an amino acid molecule passes from the lumen of the ileum to the liver
Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Amino acid molecule passes from the lumen of the ileum to the liver
through Sodium cotransporter.
The protein first of all hydrolyzed into amino acids through the enzymes
gastric and pancreatic proteases.
Amino acids are absorbed from the lumen of the ileum to the liver through
the cotransporter. This is done by it moving through the alabaster
membrane through the mechanism called facilitated diffusion and
subsequent absorption through H+ dependent cotransporters.

What are three important functions of the cell membrane?
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
