The modern synthesis combined the concepts of _______ and evolution. If a population is at Hardy-Weinberg equilibrium, the allele frequencies must be _______.
Answer:
The correct answer would be - genetics, constant.
Explanation:
The modern synthesis is a unified evolution theory that came forward by the fusion of Mendelian genetics with Darwinian evolution. It is focused on the genetic basis of evolution as it defines evolution as changes in the allele frequency in the population.
If a population is at Hardy-Weinberg equilibrium, the allele frequencies remain the same in the population unless there is no change is applied to it. It will remain constant only if there is no mutation, infinite population size, no gene flow, random mating, and no selection.
Answer:
1. natural selection
2. constant from generation to generation in the absence of other evolutionary influences.

Answer:
A dead zebra
Explanation:
Scavengers are animals that consume dead organisms that have died from causes other than predation. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. Scavengers play an important role in the ecosystem by consuming dead animal and plant material.
How does the crossing-over of chromosomes that occurs during recombination result in increased genetic variability in population?
THIS IS A TEST ANSWER
Answer:
they swap alleles
Explanation:
when homologous chromosomes cross over during meiosis, they exchange segments of DNA/swap alleles. this means that the chromosomes now have a completely unique combination of alleles, which causes variation. It is also random which of these unique chromosomes end up in which daughter cell (the gametes) and since fertilisation is a random and independent event, which unique male gamete that fertilises which unique female gamete is also random. This means the resultant zygote has a unique combination of alleles that is unlike either of their parents.

what trait only appears when a organism is a homzygous
Answer:
Both can show.
Explanation:
The genotype can look like the following:
TT <= Homzygous Dominant
tt <= Homzyogous Recessive
Tt <= Heterzygous
See? It would be hard to determine exactly which trait would show without the second half of the name! (By the way, I can't say the proper names so I apologize)
I hope this helps! ^-^
Which organelle is considered the control center of the cell or the "brain" of the cell? It contains all the DNA or the instructions to carry out the function of the cell.??
Answer:
Cell Nucleus
Explanation:
The nucleus is perhaps the most important structure inside animal and plant cells. It is the main control center for the cell and acts kind of like the cell's brain.
Como resultado del proceso de la fotosíntesis se elimina a través de los estomas a La glucosa b) El oxígeno. C) El dióxido de carbono d ) Oxígeno y dióxido de carbono
Answer:
Como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.
Explanation:
La fotosíntesis es un proceso metabólico que llevan a cabo determinadas células de organismos autótrofos, es decir, aquellas que tienen la capacidad de producir su propio alimento, como las plantas. Con este proceso, las plantas captan la energía de la luz solar y la transforman en energía química, para producir materia orgánica a través de materia inorgánica.
Los procesos que llevan a cabo las plantas en la fotosíntesis se llevan a cabo en 2 etapas: en la primera etapa las plantas absorben el agua del suelo a través de las raíces. A través de sus tallos lo transportan hasta sus hojas. En estos se encuentra el pigmento llamado clorofila, que además de darle a la hoja el color verde, capta la luz solar y rompe la molécula de agua (H₂O), separando el hidrógeno (H) del oxígeno (O₂). En esta etapa se almacena energía y se libera oxígeno al medio ambiente.
La otra etapa es capturar dióxido de carbono. Esto proporciona los átomos de carbono y oxígeno que, junto con el hidrógeno y la energía almacenada, formarán la molécula de glucosa.
Entonces, los estomas son poros en la superficie de las plantas, encontrándose mayoritariamente en las hojas y en menor medida en los tallos y otros órganos. En ellas transcurre el intercambio gaseoso mecánico, es decir que en este lugar sale el oxígeno y entra dióxido de carbono en la fotosíntesis.
Por lo que, como resultado del proceso de la fotosíntesis se elimina a través de los estomas el oxígeno.

What are new stars that are found in the spiral arms and formed from recycled dead star material known as?
population II stars
red dwarf stars
population I stars
brown dwarf stars
Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
Answer: population l stars

As skeletal muscle is further stretched beyond the length where optimum force is developed, ________. As skeletal muscle is further stretched beyond the length where optimum force is developed, ________. the thick filaments overlap one another, thereby reducing their ability to interact with actin the thin filaments overlap one another, thereby reducing their ability to interact with myosin the thick filaments are pulled away from one another, thereby reducing their ability to interact with actin the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin the amount of calcium released by the sarcoplasmic reticulum is reduced as length increases
Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.

Why would scientists conduct research on a newly discovered alternative fuel?
A. To maintain the public dependence on fossil fuels
B. To maintain the success of the petroleum industry
C. To confirm that the alternative fuel is cleaner than fuels currently used
D. To confirm that the alternative fuel increases atmospheric carbon dioxde.
Answer:
C. To confirm that the alternative fuel is cleaner than fuels currently used
Explanation:
The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.
