This Roman snail, this cuttlefish, and this mussel have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species
Answers
Complete question:
This Roman snail, this cuttlefish, and this mussel have similarities and
differences in their body structures. What does the information about these
structures tell you about the ancestors of these species?
a) None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.
b) The Roman snail and the cuttlefish share an ancestor population, but they must not share an ancestor with mussels because mussels have no radula.
c) All three species share an ancestor population, but Roman snails and
cuttlefish share a more recent ancestor population. This is why they share
the radula structure.
d) We cannot make observations of ancestor populations from the past. It is
impossible to explain ancestors with only the information about the body
structures of different species.
Answer:
The correct answer is option C. All three species share an ancestor population, but Roman snails and cuttlefish share a more recent ancestor population. This is why they share the radula structure.
Explanation:
The three species belong to the mollusk phylum, and to the placophore group.
Each of them belongs to a different class.
The Roman snail belongs to the Gasteropod class, The cuttlefish belongs to the Cephalopod class, The mussel belongs to the Bivalve class.The tree classes share a common ancestor from which all the placophores evolved. Among them, we can mention the monoplacophore, gasteropod, cephalopod, bivalve, and scaphopods. Three branches diverged from this common ancestor. The first one originated the monoplacophore. The second one originated the common ancestor of gastropods and cephalopods. And the third one originated the common ancestor of bivalves and scaphopods. The tree-mentioned species inherited the mantle and the radula from their foreign common ancestor. But later in time, individuals that originated bivalves lost the radulla. This is why the three species have a mantle, but only gastropods and cephalopods have a radula. When each of these classes evolved, they developed their own traits,
Gastropods → muscular foot used for moving Cephalopods → pallial cavity for swimmingBivalves → byssal threads to attach to the rocksYou will find an image in the attached files that will help you understand this explanation.
Which describes a way in which phosphorus may enter into the phosphorus cycle?
Earthquakes release phosphorus.
Phosphorus is carried in the rain that was evaporated from lakes.
Human use of fertilizers release phosphorus into the groundwater.
Phosphorus is transpired from the leaves of plants.
Answers
Answer:
I think the correct answer from the choices listed above is option C. A way in which phosphorus may enter into the phosphorus cycle is that when human use of fertilizers release phosphorus into the groundwater. Hope this answers the question. Have a nice day.
Human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle. Therefore, the correct statement is option C.
What is the use of phosphorus?Phosphorus is a nutrient needed by plants to grow, and it is added to soil in the form of fertilizers. When it rains, the phosphorus is washed away from the soil and carried into nearby rivers, lakes, and groundwater.
The phosphorus is then taken up by plants or become part of the sediment at the bottom of bodies of water.
Phosphorus can be transformed from there and recycled through the different parts of the phosphorus cycle, such as weathering, erosion, and sedimentation. Phosphorus can also be released from the decomposition of organic matter.
Therefore, human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle.

According to the National
Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause
problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.
Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?
O It will increase blood pressure because the ventricles are contracting with more force.
O It will increase blood pressure because the ventricles are filling with more blood between beats.
O It will decrease blood pressure because there is a longer rest period beats of the ventricles.
O It will decrease blood pressure because the ventricles are filling with less blood between beats.
Answers
Answer:
It will decrease blood pressure because the ventricles are filling with less blood between beats.
Explanation:
In ventricular tachycardia, the heart beats faster than normal, usually 100 or ... The chaotic heartbeats prevent the heart chambers from properly filling with blood. As a result, your heart may not be able to pump enough blood to your body

El efisema pulmonar,provocado princioalmente por el consumo de cigarro, es una lesion que genera destruccion de los alveolos y, por lo tanto, zonas en las que no se produce el intercambio de gases ¿que consecuencias puede tener esta lesion en el organismo?
Answers
Answer:
El enfisema pulmonar disminuye la cantidad de tejido pulmonar, disminuyendo de este modo la cantidad de oxígeno que llega a la sangre (hipoxemia). El enfisema está asociado a diferentes trastornos incluyendo infecciones respiratorias recurrentes, pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores.
Explanation:
El enfisema pulmonar es una enfermedad causada por la destrucción de los alvéolos pulmonares la cual está asociada a un aumento en la dificultad para respirar. Las principales causas de esta enfermedad son la exposición continua al humo del cigarrillo y otras sustancias nocivas para la salud, como así también a contaminantes presentes en la atmósfera. El enfisema pulmonar va progresivamente destruyendo las paredes alveolares pulmonares y los vasos sanguíneos que las recorren, disminuyendo así la elasticidad pulmonar, aumentando la proporción de aire que recorre los pulmones y de este modo también aumentando la distensibilidad pulmonar. Esta enfermedad disminuye la capacidad de oxigenar la sangre, generando una sensación constante de falta de aire (disnea) y cuadros progresivamente más severos de hipoxemia. Cuando el enfisema pulmonar se encuentra en grado avanzado, la única opción viable es el reemplazo del órgano dañado mediante un trasplante pulmonar. El enfisema puede estar asociado a infecciones respiratorias recurrentes (resfriados, gripe), pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores (tobillos, pies y piernas).

The carrying capacity for a population of frogs in a rainforest ecosystem is 840 frogs, and the maximum rate of increase for this population is 1.0 per individual per year. Using the logistic population growth model, what is the approximate population growth rate for 212 frogs?
4 frogs per year
29 frogs per year
158 frogs per year
314 frogs per year
Answers
Answer:
4 frogs per year is the answer
In logistic growth, a population's per capita growth rate gets smaller and smaller as population size approaches a maximum imposed by limited resources in the environment, known as the carrying capacity (K).
Formula used: dN/dT= rN{1-N/K}
Given: k= 840 frogs
N= 212, r= 1 year
To find: r=?
Solution:
putting value in equation:
dN/dT= rN{1-N/K}
dN/dT = 1 x 212 {1-212/840}
so, dN/dT= 158.57 ( approx)
Final answer: The correct option is (c)
158 frogs per year
Thus, we can conclude that 158 frogs per year will be the population of frogs.

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend more time?
A. Prophase
B. Mitosis
C. Meiosis
D. Interphase
Answers
Answer:b
Explanation:
The cell spends more time in the meiosis phase. Therefore, option "C" is correct.
What is meiosis?Meiosis is a type of cell division in sexually reproducing organisms, therefore, producing gametes. In this process, the number of chromosomes is reduced in the gametes. These cells are known as haploid cells. The examples are sperm and ovum.
There are two phases of meiosis: meiosis I and meiosis II. Meiosis I has four stages whereas meiosis II has three stages. In meiosis I, a cell divides into two genetically distinct haploid cells. In meiosis II, the two divided haploid cells divide further in two cells. Total four cells are produced in the process of meiosis.
Meiosis is an important cell division process in sexually reproducing organisms. It is used in the production of gametes in both males and females organisms.
Therefore, meiosis take more time than mitosis due to double stages.

Có rất nhiều lý do mà khóa tu là quan trọng! Chúng giúp chúng ta loại bỏ bản thân khỏi sự quen thuộc của những khuôn mẫu thông thường hoặc môi trường xung quanh, để dành thời gian để đến với Đức Chúa Trời trong sự Sáng tạo của Ngài. Thông thường ở những thời điểm khác nhau trong cuộc sống, một lý do hoặc nhu cầu này có thể vượt trội hơn lý do khác. Tuy nhiên, luôn có những lý do chính đáng, bất kể mùa nào trong đời của bạn, rằng một khóa tu là rất quan trọng để lên lịch, lập kế hoạch và tham dự. Dưới đây chỉ là bốn trong số chúng và chúng tôi nghĩ bạn có thể nghĩ ra nhiều hơn nữa!
Gần như hàng ngày, chúng tôi nhận được các cuộc gọi hoặc chuyến thăm từ những người đã đến Wafloy hơn 20, 30, 40 năm trước. Niềm vui khi trở thành một trung tâm nhập thất 72 tuổi là chúng tôi được nghe những người khác chia sẻ những kỷ niệm đó. Mối liên kết của những ký ức này không chỉ buộc họ với một nơi, mà còn với tình đồng nghiệp của những người khác đã đi cùng một hành trình. Chúng ta, con người, được tạo ra để giao tiếp với Chúa và với nhau. Dành thời gian như một nhóm, cô lập trong bầu không khí phát triển và dễ bị tổn thương có thể cho phép Đức Chúa Trời di chuyển trong cuộc sống. Điều này sẽ tạo ra những ký ức gắn kết vượt ra ngoài bản thân sự kiện khóa tu. Những ký ức đó và tác động của chúng có thể tồn tại suốt đời.
